Answer:
The answer is 4x+28.
Step-by-step explanation:
Using distributive property, what you do on one side you do to the other.
4(x+7) is a multiplication problem, so you have to multiply 4 by x and 4 by 7.
4*x=4x
4*7=28.

Answer:
A
Step-by-step explanation:
Surface area = 17*(sqrt(1155) + 19)
h^2 = 19^2 - 17^2/4
=> h = sqrt(4*19^2 - 17^2)/2 = sqrt(1155)/2
Surface area = 4(1/2*h*17) + 17*19 = 17(sqrt(1155) + 19)
