Plug in 2 for x, and -4 for y
2(2)² + 3(2)(-4) - (-4)²
2² = 4(2) = 8
3(2) = 6(-4) = -24
-4² = 16
8 - 24 - 16 = answer
Simplify.
answer = 8 - 40
answer = -32
-32 is your answer
hope this helps
That is very cool and rare if you did it nice job!
Step-by-step explanation:
12(6) - 7(2) + (6-3)
48 - 14 + 2
36
divide 3 by 4 = 3/4 = 0.75
so Cody jogs 3/4 mile for every 1 mile Vanessa runs
Step-by-step explanation:
4x + 2xy=
4×4 + 2×4×-3
= 16 + (-24)
= - 8
