Question

Evaluate the expression w 2 - v + 1 for w = -2 and v = -8.

A. 5
B. 13
C. -11
D. -3

Answer 1

A. 5
-2*2=-4-(-8)= -4+8=4+1=5

Answer 2

w² - v + 1

(-2)² - (-8) + 1

4 + 8 + 1 = 13

B.13 is your answer

(two negatives = one positive)*
(plug in -2 for w, and -8 for v)
(is that w², or do you mean 2w?)

hope this helps
