( -5 x 3 y 4 + 9x) + (- 5 x 3 y 4 - 8 x+8 x 2 y 2) (
- 8 x 2 y 2 + 18 x 3 y 4)

.25

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

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

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

493 would be the correct answer
