Answer:
The answer is 60
Step-by-step explanation:
I am going to assume that A and a are the same variable. For future reference, a and A wouldn't be considered the same variable so be careful with that :)
We can first plug in 2 for a and 4 for b
4(2) + 2(4^2) - 2(2 - 3(4))
8 + 2(16) - 2(2 - 12)
8 + 32 - 2(-10)
8 + 32 - (-20)
8 + 32 + 20
60
Answer:
d. (9, 13)
Step-by-step explanation:
5x-3y=6 /*6
6x-4y=2 /*(-5)
30x - 18y = 36
<u>-30x +20y = - 10</u>
2y = 26
y = 13
5x-3y=6
5x - 3*13 = 6
5x - 39 = 6
5x = 45
x = 9
(9, 13)
