Step-by-step explanation:
Formula = A=2(wl+hl+hw)
=> A=2(wl+hl+hw)
=> A = 2((2)(4)+(2.5)(4) + (2.5)(2))
=> A = 2(8 + 10 + 5)
=> A = 2(23)
=> A = 46
Surface area = 46

Answer:
Option B
Step-by-step explanation:
we know that
The critical point of a function are the points on the graph of a function where the derivative is zero or the derivative does not exist.
we have
step 1
Take the derivative of the function
step 2
Set that derivative equal to 0 and solve for x. Each x value you find is known as a critical number
<em>Alternative Method</em>
The critical point of the quadratic equation is the vertex, because the function changes from decreasing to increasing at that point (In this problem the vertex is a minimum)
we have
Convert into vertex form
the vertex is the point (-2,-15)
therefore
The x-coordinate of the critical point is x=-2
