Answer:
X= -4
Step-by-step explanation:
First you subtract both sides by 3. You will get:
5x=-20
then you divide both sides by 5
-20/5=-4 so
x=-4
Answer:x^8+7x^4
Step-by-step explanation:
First we have to do the g(x) cause it's closest to x.
g(x)=x^4
x^4 is the output for g(x) ad input for f(x). So now we have to put it in x's place in here➡️f(x)
So, f(x^4)=(x^4)^2+ 7(x^4)
=x^8+7x^4
It's the final output
A.) Let x be the number of swimming lessons she had, then
402 - 15x = 237
b.) 15x = 402 - 237 = 165
x = 165/15 = 11
She had 11 swimming lessons
c.) Let the number of lesson she had be y, then 19y = 237
y = 237/19 = 12 lessons
She can pay for 12 lessons with her remaining $237.

Answer:
11x^2 −6x−9
Step-by-step explanation:
9x^2 – 10x + 1 - ( -2x^2) + 4x – 10.
The opposite of −2x^2 is 2x^2
9x^2
−10x+1+2x
^2
+4x−10
Combine 9x^2 and 2x^2 to get 11x^2
.
11x^2
−10x+1+4x−10
Combine −10x and 4x to get −6x.
11x^2
−6x+1−10
Subtract 10 from 1 to get −9.
11x^2 −6x−9
