9x * x = 9x
9x * 4 = 36x
-8 * x = -8x
-8 * 4 = -32
Combine like terms.
36x - 8x = 28x
The answer would be the fourth option.
Answer:
I think option D is correct
15 + .5x = 25
Step-by-step explanation:
.5x = 10
x = 20
The true statements are A and D
4 (3(3) + 4) is 52, while 16(3) + 12 is 60
that would not be equivalent in w = 3 but it would in w = 1
