write your answer as a polynomial in simplest form.
(f•g)(x)=
Answer: (f•g)(x)=2x²+12x
Step-by-step explanation:
(f•g)(x) is the same as saying f(x)•g(x). Since we have f(x) and g(x), we can just multiply them together.
(f•g)(x)=2x(x+6) [distribute by FOIL]
(f•g)(x)=2x²+12x
Now, we know that (f•g)(x)=2x²+12x.

Solve 0.5y+y/3=0.25y+7
please answer this question
Answer:
y = 28
Step-by-step explanation:
0.5y + y/ 3 = 0.25y + 7
1.5y / 3 = 0.25y + 7
y/2 = 0.25y + 7
y = ( 0.25y + 7)*2
y = 0.5y + 14
y - 0.5y = 14
0.5y = 14
y = 14/0.5
y = 28

The dashed triangle is a dilation image of the solid triangle. What is the scale factor? A. 1/4 B. 1/2 C. 2/3 D. 2
Answer:
I am not good in maths but I think it is
A 1/4
A model's scale ratio is the ratio of linear dimensions. The scale factor of the triangle is (1/2).
What is the scale ratio?A model's scale ratio is the proportionate ratio of a linear dimension of the model to the equivalent characteristic of the original.
The scale ratio of the triangle can be found by taking the ratio of any one side of the dashed triangle to the solid triangle. Therefore, the scale ratio will be,
[tex]\rm Scale\ ratio = \dfrac{\text{Length of the dashed line}}{\text{Length of the solid line}}\\\\ Scale\ ratio = \dfrac{2}{4} = \dfrac{1}{2}[/tex]
Hence, the scale factor of the triangle is (1/2).

jamie's string is 10ft 1in long. emma's string is 6ft 4in long. how much longer is jamie's string
Answer:
Jamie's string is 3ft and 9in
Step-by-step explanation:
10ft 1in
-6ft 4in
=3ft 9in
Answer:
3ft 9 in
Step-by-step explanation:
So, in each foot there's 12 inches. Knowing that, the operation you use is subtraction. So you do 10 ft 1 in - 6 ft 4 in. If you do that operation knowing that 12 inches=1 foot, then you should get 3 ft 9 in.

18 is 2/3 of what number
The number 18 is 2/3 of the number 27.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that 18 is 2/3 rd of the number. The value of the unknown number will be calculated as,
2 / 3 x = 18
x = ( 18 x 3 ) / 2
x = 9 x 3
x = 27
Therefore, the unknown number will be 27.

O d
0.681
Answer: The answer is B i just did this test
Step-by-step explanation:
The only number on the list that matches the rounding requirement is 0.579. Hence, the correct option is B.
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
We can consider what the offered numbers are when they are rounded to hundredths:
0.574 ⇒ 0.57
0.579 ⇒ 0.58 . . . matches the requirement
0.585 ⇒ 0.59
0.681 ⇒ 0.68
The only number on the list that matches the rounding requirement is 0.579.
Hence, the correct option is B.
