8 = 8v - 4 (v + 8)
Distribute the 4 through the parentheses
8 = 8v - 4v - 32
combine like terms
8 = 4v - 32
add 32 to both sides
8 + 32 = 4v -32 + 32
combine like terms
40 = 4v
divide each side by 4
40/10 = v
4 = v
v= 4

Your answer is B. 12.
12 kids are unaccounted for after you subtract the kids that take A1, then A2, the both subjects.
For this case we have the following expression:
-x (7x + 2) + x ^ 2
Rewriting we have:
(-7x ^ 2 -2x) + x ^ 2
Adding similar terms we have:
-6x ^ 2 - 2x
Answer:
The simplified expression is given by:
-6x ^ 2 - 2x
