f(x) = x^2 + 16x
Completing the square.
f(x) = a(x-h)^2 + k
f(x) = (x + 8)^2 - 64
h = -8, k = -64
Vertex = (h,k)
Vertex = (-8, -64)

Answer:
40b - 4b or 36 b
Step-by-step explanation:
No. of tomatoes in each box = 40
No. of box shipped = b
No. of tomatoes in those b box = b*No. of tomatoes in each box = 40b
No. of tomatoes damaged in each box = 4
No. of box shipped = b
No. of tomatoes damaged in those b box = b*No. of tomatoes damaged in each box = 4b
Thus, total no. of tomatoes that can be sold by store = No. of tomatoes in those b box - No. of tomatoes damaged in those b box = 40b - 4b
Algebraic expression to express the no. of tomatoes that can be sold from those b box is
40b - 4b = 4b(10-1) = 4b(9) = 36b (Answer)
ANSWER
The correct answer is
EXPLANATION
The expression given to us is,
We plug in
. That means we substitute 12 wherever we see x to obtain,
We simplify the parenthesis first to obtain,
Hence the expression evaluates to
