Answer:

-2x^3+x^2+5x-5

Step-by-step explanation:

f(x) = 4 - 2x – 2x^3

g(x) = x² + 7x-9

f(x) + g(x)=4 - 2x – 2x^3+ x² + 7x-9

Combine like terms

f(x) + g(x) = -2x^3+x^2+5x-5

Kaya used these steps to solve the equation 7+2x=2(x−1)+4. Which choice describes the meaning of her result, 7=2?

leva [86]

Answer:

the equation has no solution

Step-by-step explanation:

Given

7 + 2x = 2(x - 1) + 4 ← distribute and simplify the right side

7 + 2x = 2x - 2 + 4

7 + 2x = 2x + 2 ( subtract 2x from both sides )

7 = 2 ← not possible

This indicates that the equation has no solution
