6x + 9
I hope this helps!
Answer:
= 6x +9
Step-by-step explanation:
1. you need to multiply -3 by x² + 2x - 3
so you got -3x² -6x + 9
2. Then, you need to multiply 3 by (x²+4x)
= 3x² + 12x
3. -3x² - 6x + 9 + 3x² + 12x
4. then you need to solve with the same
= - 3x² + 3x²
= 0
= - 6x + 12x
= 6x
5. lastly you will got the answer.
# = 6x +9
if 13sinA=5 evaluate 5 sinA -2 cosA/tanA
Answer:
Step-by-step explanation:
We have
[tex]\sin A=\frac{5}{13}[/tex]
Draw a right triangle where the side in front of the angle A is 5 and the hypothenuse is 13. Hence the length of the other angle is [tex]\sqrt{13^2-5^2}=12[/tex].
It follows that
[tex]\cos A=\frac{12}{13}[/tex] and [tex]\tan A= \frac{5}{12}.[/tex]
Subtitute this we obtain
[tex]5\sin A-\frac{2\cos A}{\tan A}=5\cdot \frac{5}{13}-\frac{12/13}{5/12}[/tex]
which is equal to
[tex]\frac{25}{13}-\frac{144}{65}=\frac{125-144}{165}=-\frac{19}{165}.[/tex]
Convert 37.45 to a fraction
Answer:
37 9/20
Step-by-step explanation:
Answer:
[tex]{ \bf{answer \: is \: { \underline{37 \frac{9}{20} }}}}[/tex]
Step-by-step explanation:
When converting to fraction, you must get to know about the place values.
3 » tens
7 » ones
.4 » tenth
5 » hundredth
since last place value is hundredth, fraction denominator must be 100
therefore:
[tex]37.45 = \frac{3745}{100} [/tex]
then you can reduce by 5:
[tex] = \frac{3745 \div 5}{100 \div 5} \\ \\ = \frac{749}{20} [/tex]
In mixed fraction:
[tex] = 37 \frac{9}{20} [/tex]

If point P(2,-4) is reflected over the x-axis, determine the coordinates of the image.
(-2, -4)
(-4, 2)
(4, 2)
(2, 4)
Answer:
(2,4)
Step-by-step explanation:
the x values stays the same because you are reflecting over its axis. the 4 becomes positive
Step-by-step explanation:
Algebra Explanation: If something is reflected over the x axis, the x coordinate's sign will stay the same while the y coordinate sign will switch.
Using this info, the answer will be (2,4)
Geometric Explanation: Point P is in Quadrant 4. If we reflect a point about the x axis, it can only go to Quadrant 1. Quadrant 1 has a positive x and positive y. So this eliminates the first 2 options.
Reflecting across a line will align the pre image and current image with each other. This means the x coordinate and y coordinate will stay in the same place. So (2,4) is the answer.

Step-by-step explanation:
[tex]2-\frac{1}{8}y=11+\frac{7}{8}y[/tex]
➠ Subtract 2 from both sides:-
[tex]2-\frac{1}{8}y-2=11+\frac{7}{8}y-2[/tex]
[tex]-\frac{1}{8}y=\frac{7}{8}y+9[/tex]
➠ Subtract 7/8y from both sides:-
[tex]-\frac{1}{8}y-\frac{7}{8}y=\frac{7}{8}y+9-\frac{7}{8}y[/tex]
[tex]-y=9[/tex]

this is my brothers math homework can someone help w the what is the meaning question
The answer is [tex]24/4=6 \hspace{0.1cm} and \hspace{0.1cm}4*6=24[/tex]. "unknown factor" pertains to finding an unknown value in a multiplication problem, while "quotients" refer to the results obtained in division operations.
Both concepts are fundamental in arithmetic and algebraic calculations.
In mathematics, "unknown factor" and "quotients" are related to multiplication and division, respectively:
1. **Unknown Factor:**
- An "unknown factor" refers to a number or variable that you want to find or determine in a multiplication problem.
- In the context of an equation like "a * b = c," where "a" and "b" are known values or variables, and "c" is the result of the multiplication, you might be trying to find the value of "a" or "b." The unknown factor is the value that you don't initially know, and you need to solve for it.
- For example, if you have the equation "3 * x = 15," the unknown factor is "x," and to find its value, you would need to divide both sides of the equation by 3, yielding "x = 5."
2. **Quotients:**
- "Quotients" is the plural form of "quotient," and it refers to the result of a division operation.
- In division, the quotient is the number that you get when you divide one number (the dividend) by another number (the divisor).
- For example, in the division problem "12 ÷ 4," the quotient is 3 because 12 divided by 4 equals 3. Here, 3 is the result or quotient of the division operation.
- Quotients can be whole numbers, fractions, or decimals, depending on the numbers being divided and the division process.

|3x-8|+7=2
Answer:
No solution
Step-by-step explanation:
To solve first you need to isolate the absolute value sign. Do this by subtracting 7 from each side.
|3x-8| = -5Now an expression inside absolute value bars is set to a negative. Since absolute value makes terms and expressions positive, there is no x-value that could make this true. Therefore, there are no solutions.
[tex]\\ \tt\Rrightarrow |3x-8|+7=2[/tex]
[tex]\\ \tt\Rrightarrow |3x-8|=2-7[/tex]
[tex]\\ \tt\Rrightarrow |3x-8|=-5[/tex]
Because of absolute vale there is no solution
1. a. In an examination, 60 candidates sat for either Mathematics or English language 20% passed in Mathematics only and 40% passed in English language only.

Find the width of a cuboid with height 8m and length 12m, given that the volume is 480m ii. Calculate the total surface area of the cuboid b. Find the truth set of: 1 - m + m -3 = 6 5 4
A.)
Total Number of students = 60
Since each candidate passed in atleast one of English and Math ; the none of the students failed.
Percentage who passed :.
Mathematics only = 20%
English only = 40%
Since, no one failed ; percentage that passed both = 100% - (40+20)% = 40%
Number who passed Mathematics only :
20% × 60 = 12 students
Number that passed English only :
40% × 60 = 24 students.
Number that passed both = (40% × 60) = 24 students
Number that passed English = (Number that passed English only + Number that passed both) = 24 + 24 = 48
.Number that passed mathematics = (Number that passed Maths only + Number that passed both) = 12 + 24 = 36
2.)
Total daddy has = 50
Half given to mummy = 1/2 × 50 = 25
Amount given to houseboy = 10
Amount left = 50 - (25 + 10) = 15
Fraction of Amount left = 15/50 = 3/10
C.)
Length of cuboid = 12
Height = 8 cm
Volume of cuboid = 480
Width = w
Recall :
Volume = Length × width × height
480 = 12 × 8 × w
480 = 96w
w = 490 / 96
w = 5
Width of the cuboid = 5
The surface area of a cuboid : 2(lh + lw + hw)
Hence,

Step-by-step explanation:
Lets start with the 9 kids
to find out how much each one paid you divide by the amount of money
72/9=8
Each child pays 8 dollars
If only 6 kids go we multiply 8 and 6
since each of them are paying 8 dollars

The diameter of a circle is 3ft find its area to the nearest 10th
Answer:
6ft
Step-by-step explanation:
the 3 ft is multiple to 3
Answer:
A ≈ 7.1 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = πr² ( r is the radius )
Here diameter = 3 , then r = 3 ÷ 2 = 1.5 , then
A = π × 1.5² = 2.25π ≈ 7.1 ft² ( to the nearest tenth )
A table increased in price by 4/5. After the increase it was priced at £117. What was the original price of the table?
Answer:
£65
Step-by-step explanation:
The original price of the table is unknown, so let x = original price of the table.
The price, x, increased by 4/5 of the price, so the increase is 4/5 x.
The total price after the increase is x + 4/5 x = 5/5 x + 4/5 x = 9/5 x.
The price after the increase is £117.
9/5 x = 117
5/9 * 9/5 x = 5/9 * 117
x = 65
Answer: £65
Answer:
£ 93.60 p
Step-by-step explanation:
I am not sure if I am fully correct but what I did , I divide 117 / 5 and then x by 4 to give me the price
(117/5 ) x 4 = £ 93.60 pence
117 / 5 = £ 23.40 p x 4 = £ 93.60 pence
