Answer:
-0
Step-by-step explanation:
W = -3
X = 3
Z = -9
Y = 6
-3 + 3 = 0
-9 + 6 = -3
-3 + 0 = -3
Then -3 is closest to -0! Cause when rounding, 4 and under as an example as 24 the round will be 20! And 25 will be 30
You are basically just adding, so combine like terms.
3x^2 + 5x^2 = 8x^2
6x - 2x = 4x
4 - 8 = -4
So the answer is D.
