Try this solution:
There are several ways to find the max or min of the given function:
1. to use derivative of the function. For more details see the attachment (3 basic steps); the coordinates of max-point are marked with green (-5; 14.5)
2. to use formulas. The given function is the standart function with common equation y=ax²+bx+c, it means the correspond formulas are (where a<0, the vertex of this function is its maximum):


Finally: point (-5;14.5) - maximum of the given function.
3. to draw a graph.
The length of one edge would be 2 fr
C.

Answer: CD segment
Step-by-step explanation:
Answer:
90 in²
Step-by-step explanation:
The lateral area can be found using the formula ...
LA = (1/2)Ph
where P is the perimeter of the base and h is the slant height. For your dimensions, the lateral area is ...
LA = (1/2)(3×5 in)(12 in) = 90 in²
The lateral area is 90 square inches.
