Answer:
assuming the value x = 1/3 and y = 1/4
so if you use both value in an addition equation, you'll get this equation :
[tex] \frac{1}{3} + \frac{1}{4} [/tex]
which then you can simplify by making both fraction have the same value :
[tex] \frac{1}{3} \times \frac{4}{4} + \frac{1}{4} \times \frac{3}{3} [/tex]
[tex] \frac{4}{12} + \frac{3}{12} [/tex]
therefore you get the answer :
[tex] \frac{7}{12} [/tex]
So this equation shows that the denominator 3 and 4 are related to 12.
The denominators 3 and 4 are related to 12 in a multiplication equation, you can express it as 1/3 * 1/4 = 1/12
The denominators 3 and 4 are related to 12 in a multiplication equation, you can express it as:
1/3 * 1/4 = 1/12
In this equation, the product of 3 and 4 (which is 12) represents how the denominators 3 and 4 combine to give the common denominator of 12. In fractions, when you need to find a common denominator to add or subtract fractions with different denominators, you can use this multiplication relationship. For example, if you have fractions with denominators 3 and 4, you can convert them to fractions with a common denominator of 12 by multiplying both the numerator and the denominator of each fraction by the appropriate factor to get:
1/3 = (1 * 4) / (3 * 4) = 4/12
1/4 = (1 * 3) / (4 * 3) = 3/12
Now both fractions have a common denominator of 12, and you can easily add or subtract them.

Answer:
138.2
Step-by-step explanation:
find area of small circle and subtract from area of big circle
A=pi*r^2
A=pi*12^2
A=144pi
A=pi*r^2
A=pi*10^2
A=100pi
144pi-100pi=44pi
44pi=138.2
Answer:
Step-by-step explanation:
Area of shaded region = A of outer circle - A of inner circle
r of outer circle = 12 cm
r of inner circle = 10 cm
Now,
As we know, area of circle = [tex]\pi r^2[/tex]
=> [tex](\frac{22}{7} * 12^2) - (\frac{22}{7} * 10^2)[/tex]
= 452.57 - 314.28
= 138.29 cm sq
Round off to nearest tenth = 140 cm sq

Answer: [tex]2x^2[/tex] + 7x + 5
Step-by-step explanation:
--> No. of blocks of [tex]x^2[/tex] = 2
So, 2 * [tex]x^2[/tex] = [tex]2x^2[/tex]
--> No. of blocks of x = 7
So, 7 * x = 7x
--> No. of blocks of 1 = 5
So, 1 * 5 = 5
∴ Hence, [tex]2x^2[/tex] + 7x + 5 is the answer.

(27) [tex]7x^2[/tex] + 9x + 2
= [tex]7x^2[/tex] + 7x + 2x + 2
= 7x(x+1) + 2(x+1)

Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62
then the subtraction
44.62 - 17 = 27.62

A rectangular patio has an area of 2x² + 13x — 24 ft2. Use factoring to find possible dimensions of the patio. The patio is to be enlarged so that each dimension is 2 ft greater than it was originally. What are the new dimensions of the patio? What is the new area of the patio?
Answer:
Step-by-step explanation:
[tex]2x^2[/tex] + 13x - 24 to be factorised to find the dimensions:
[tex]2x^2[/tex] + 13x - 24
= [tex]2x^2[/tex] + 16x - 3x - 24
= 2x(x+8) - 3(x+8)
= (2x-3)(x+8)
Length = (2x-3)
Breadth = (x+8)
∴ Increasement in length = 2x - 3 +2 = (2x -1)
Increasement in breadth = x + 8 + 2 = (x+10)

A study was conducted comparing the speeds of 2 different fish, Fish A and Fish B. The table shows the distance, in meters, Fish A travels in seconds. Scientists
concluded that Fish B travels 3 meters every 2 seconds.
Assuming both fish swim at a constant rate, which fish swims faster and by how many meters per second?
Answer:
Fish A travels faster and by 0.1 meters per second.
Step-by-step explanation:
According to the table, you can see that the seconds are not being measured constantly. To determine the rate of change of meters per second, we can use subtraction on both the numerator and denominator of the expression. Where we divide it into 1 second.
meters/second → 4.8 – 1.6 / 3 – 1 = 3.2 / 2 =
1.6 meters/second.
Now we can compare the rate from fish B by also diving it into 1 second.
3 meters every 2 seconds → 3/2 =
1.5 meters/second.
Since 1.6 > 1.5, Fish A is faster!
And to compare the simplified rates
1.6 – 1.5 = 0.1 meters.
So Fish A is 0.1 meters faster!

Find the 3 smallest positive x-intercepts of the graph of
y = cos(12x) + cos(16x) and list them in increasing order.
Please give your answers as a list of x-coordinates from least to greatest.

[tex]\cos(12x)+\cos(16x)=0 \\ \\ 2\cos(2x)\cos(14x)=0 \\ \\ \cos(2x)\cos(14x)=0[/tex]
If [tex]\cos(2x)=0[/tex], then [tex]x=\frac{\pi}{4}, \frac{3\pi}{4}, \frac{5\pi}{4}, \cdots[/tex].
If [tex]\cos(14x)=0[/tex], then [tex]x=\frac{\pi}{28}, \frac{3\pi}{28}, \frac{5\pi}{28}, \cdots[/tex].
So, the three smallest positive [tex]x[/tex] intercepts are [tex]\frac{\pi}{28}, \frac{3\pi}{28}, \frac{5\pi}{28}[/tex].

In front of a school are several gardens in rectangular raised beds. For each of the areas of a rectangular garden given, use factoring to find possible dimensions. Could the garden be square? If so, explain why.
a. x² + 32x + 256
b. x² — 4y²
c. x²- 20x + 100
Answer:
Step-by-step explanation:
(a) [tex]x^2[/tex] + 32x + 256
Factorisation by pairing:
([tex]x^2[/tex] + 16x) + (16x + 256)
= x(x+16) + 16(x+16)
= (x+16)(x+16)
∴ Side of the square = (x+16)
(b) [tex]x^2 - 4y^2[/tex]
Identity: [tex]a^2 - b^2[/tex] = (a+b)(a-b)
[tex](x)^2 - (2y)^2\\[/tex]
= (x+2y)(x-2y)
∴ Length of rectangle = (x+2y)
Breadth of rectangle = (x-2y)
(c) [tex]x^2 - 20x + 100[/tex]
[tex]= x^2 - 10x - 10x +100x[/tex]
= x(x-10) -10(x-10)
= (x-10)(x-10)
∴ Side of square = (x-10)
The factorization of the polynomial x²-20x+100 is (x-10)(x-10).
What is factorization?The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.
a) x²+32x+256
By using splitting middle term method, we get
x²+16x+16x+256
= x(x+16)+16(x+16)
= (x+16)(x+16)
b) x²-4y²
Using the identity a²-b²=(a+b)(a-b)
Now, x²-(2y)²
= (x+2y)(x-2y)
c) x²-20x+100
By using splitting middle term method, we get
x²-10x-10x+100
= x(x-10)-10(x-10)
= (x-10)(x-10)
Therefore, the factorization of the polynomial x²-20x+100 is (x-10)(x-10).

Let theta be an angle such that cos(theta)=-1/9 and 0<=theta<=2pi
Assume that cos(theta/2)<0. Then if
Terminal point of theta/2 = (a_1, a_2),
enter a_1 and a_2 in that order.
Using the cosine half angle formula,
[tex]\cos \frac{\theta}{2}=-\sqrt{\frac{1-\frac{1}{9}}{2}}=-\frac{2}{3}[/tex]
Using the sine half angle formula,
[tex]\sin \frac{\theta}{2}=\sqrt{\frac{1+\frac{1}{9}}{2}}=\frac{\sqrt{5}}{3}[/tex]
