A perfect square is a number which contains a a factor that involves a number multiplied by itself. You could also say a perfect square, when taken the square root of such a number, involves a whole number answer. Either explanation would work, and there are surely mainly more haha. 25 is the perfect square because 5×5 is a factor of 25, while 50 doesn't have a factor of the same numbers.
Answer:
I don't know I'm sorry I will tell you another answer asks me to

Step-by-step explanation:

We are given D = 16 ft, which means that r = (1/2)D = 8 ft. Therefore, the surface area of the sphere is

F(x) = -2 (x-9)2 + 14
= -4(x-9) + 14
= -2 [ 2(x-9) -7 ]
= -2 (2x -18 -7)
= -2 (2x -25)
