What is meant by the term factorization?A polynomial can be published as the product of the its factors with degrees below or equal to the degree of the original polynomial. Factorization of polynomials refers to the process of factoring.The basic technique for factoring polynomials is to find the greatest common factor, which simplifies the problem.The second factoring technique is known as grouping. If there is no factor common to all of the terms of the a polynomial, but there are factors common to a few of the terms, this method is used.The given expression is;
= (10x³ - 2x² + 8x)/2x
Take 2x common on the numerator.
= 2x(5x² - x + 4)/2x

Determine which set of side measurements could be used to form a right triangle.

square root of 8, 5, square root of 17
square root of 2, square root of 7, 9
Answers
There is no set of sides used to form a right triangle.
Right triangle:
The one angle is always 90° or the right angle. The side opposite angle of 90° is the hypotenuse. The hypotenuse is always the longest side. The sum of the other two interior angles is equal to 90°.
Let a = height of a triangle
b = base of a triangle
c = hypotenuse of a triangle
So we have formula for right triangle:
c² = a² + b²
So from this, we have
a)a = 9, b = 11, c= 13
13² = 9² + 11²
169 = 81 + 121
169 ≠ 202
Therefore the side given is not a right triangle.
b) 6, 12, 17
17² = 6² + 12²
289 = 36 + 144
289 ≠ 180
So the side given is not of a right angle triangle.
c) 8, 5, 17
17² = 8² + 5²
289 = 64 + 25
289≠ 89
So the given side is not of a right angle triangle.
d) 2, 7, 9
9² = 2² + 7²
81 = 4 + 49
81 ≠ 53
So the given triangle is not a right angle triangle.

Based on this information, of the next 3000 pizzas he sells, how many should he expect to be stuffed crust? Round your answer to the nearest whole number.
Do not round any intermediate calculations.
Answers
Valentino's Pizzeria should anticipate selling 563 Stuffed crust pizza.
What is termed as the probability?The term "probability" refers to the likelihood of a specific event (or set of events) occurring, demonstrated on a linear scale from 0 (impossibility) to 1 (certainty), as well as as a percentage between 0 and 100%. Statistics is the study of events controlled by probability.The data for the type of crust on the pizza and the number of pizzas sold are given.
Thin crust: 299
Thick crust: 228
Stuffed crust: 168
Pan style: 199
Total pizza = 299 + 228 + 168 + 199
Total pizza = 894
The frequency with which a Stuffed crust pizza is sold = 168/894 = 28/149.
As a result, if Valentino's Pizzeria sells 3000 pizzas, this same expected number of Stuffed crust pizza sold is calculated by the given formula.
Number of Stuffed crust pizza Sold = Purchase Frequency of Stuffed crust pizza X Total Sales.
= 28/149 × 3000
= 563.75
= 563 pizza.
Thus, Valentino's Pizzeria should anticipate selling 563 Stuffed crust pizza.

Jamal is 8 years older than Autumn. In 2 years the sum of their ages will be 70. How old is Jamal now?
Answers
We know that
• Jamal is 8 years older than Autumn.
,• In 2 years the sum of their ages will be 70.
Each statement above has to be expressed as an equation. Notice that "8 years older" means +8. So, the equation about the first statement is
[tex]J=A+8[/tex]Now, "in 2 years" means we have to add 2 units to each age, also we have to add them to get 70. The equation about the second equation is
[tex](A+2)+(J+2)=70[/tex]We reduce like terms
[tex]A+J+4=70[/tex]Then, we subtract 4 on each side
[tex]\begin{gathered} A+J+4-4=70-4 \\ A+J=66 \end{gathered}[/tex]Now, we replace the first equation into the last one above.
[tex]\begin{gathered} A+A+8=66 \\ 2A+8=66 \end{gathered}[/tex]We subtract 8 on each side
[tex]\begin{gathered} 2A+8-8=66-8 \\ 2A=58 \end{gathered}[/tex]At last, we divide the equation by 2
[tex]\begin{gathered} \frac{2A}{2}=\frac{58}{2} \\ A=29 \end{gathered}[/tex]Therefore, Autumn is 29 years old.Let's find Jamal's age.

There are a lot more, but for the basics of ratios you only need to know this:
- The order is very important in the ratio, whatever number came first stays in that order.
- You can only multiply or divide the same numbers. For instance, if the ratio was 1:2, you would multiply or divide the numbers by the same number.
- When you multiply or divide the ratio/numbers, you cannot not only do whole numbers, but also decimals like 0.25 or mixed decimals like 1.5.
- Remember numbers are infinite, so you can multiply or divide your ratio/numbers by any decimal or number.

There are 96 new houses being built in a neighborhood. Last month, 1/3 of them were sold. This month, 1/8 of the remaining houses were sold. How many houses are left to be sold?
Answers
Using the given fractions we can say that there are 56 houses left to be sold.
A fraction, which also denotes a component of a whole, or a ratio is any number divided into equal parts. When expressed in common English, a fraction, such as one-half, eight-fifths, or three-quarters, specifies the number of components of a specific size.
1/3 of 96 were sold...
number of houses sold = 1/3 × 96 = 96/3 = 32
So the first month 32 houses were sold.
Number of houses left = 96 - 32 = 64 houses.
number of houses sold next month = 1/8 × 64 = 64/8 = 8
8 houses were sold the second month
number of houses left 64 - 8 = 56
Therefore using the fractions 56 houses were left to be sold.

Write the polynomial function of least degree with real coefficients in standard form:
According to the complex conjugate root theorem, if a complex number a+ib is a zero of a polynomial, then its conjugate a-ib is also a zero of than polynomial.
–3 + 4i is zero of the polynomial. So, by complex conjugate root theorem -3-4i is also a zero of required polynomial.
If c is a zero of p(x), then (x-c) is a factor of p(x).
–2, –4, –3 + 4i, -3-4i are zeroes of the polynomials. So, (x+2), (x+4), (x+3-4i), (x+3+4i) are the factors of the required polynomial.

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
So, we can see that there is only 1 favorable outcome. Then we can write out the following quotient:
[tex]P(\text{roll) =}\frac{\text{favorable outcome}}{\text{total outcomes}}=\frac{1}{36}[/tex]3) Hence, the answer is 1/36
The difference between two numbers is 22. The sum of twice the smaller number and 3 times the greater number is 246.
Answers
Given:
The difference between two numbers is 22.
The sum of twice the smaller number and 3 times the greater number is 246.
Required:
To find the two numbers.
Explanation:
Let the two numbers be x and y.
Let y be the smaller number.
The difference between two numbers is 22.
[tex]x-y=22[/tex]The sum of twice the smaller number and 3 times the greater number is 246.
[tex]2y+3x=246[/tex]Now
[tex]\begin{gathered} 2y+3(22+y)=246 \\ 2y+66+3y=246 \\ 5y=246-66 \\ 5y=180 \\ y=\frac{180}{5} \\ y=36 \end{gathered}[/tex]Now x is,
[tex]\begin{gathered} x-36=22 \\ x=22+36 \\ x=58 \end{gathered}[/tex]Final Answer:
The two numbers are 58 and 36.

Answer:
Statement: ∠XYZ = ∠ABC Reasons: Below
Step-by-step explanation:
For two angles to be complementary means that the sum of the two angles is equivalent to 90°. When an angle has one of those little squares, that means the angle is a right angle, or a 90° angle. Also, since it's given that line segment AB and line segment BC are perpendicular, this means the two lines/line segments cross each other at a right angle, which also proves that line segment AB and BC have a 90° angle.

If l is parallel m and r parallel s explain how you know Angele 1 and Angle 6 are supplementary
Answers
Angle 4 and angle 6 are supplementary to each other.
Given : the two line r and s are parallel to each other and there are two transversals
And thus angle 6 and angle 4 are equal because angles corresponding angles are equal. This is because of a theorem which states that angles on the same side of the two parallel lines are equal .
And this further implies that the angle adjacent to angle 4 and angle form will form an angle whose sum would be equal to 180 degree. That is they will form a supplementary angle .
And this angle and angle 1 are equal because these two angles are corresponding angles and as mentioned above because of that theorem they are equal.
Thus from these two above mentioned arguments it is clear that angle 4 and angle 6 are supplementary angles .
