Carmine is packing 27 superballs in 3 square layers into a cubed shaped box. Each ball has diameter 4 cm. All 3 lays fit exactly into the box when stacked (a) What is the volume of the box?
(b) What is the surface area of the box?

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

What is the solution of sqrt x+2-15=-3

The sum of the reciprocal of a positive number and the reciprocal of 2 more than the number is 3/4 equation: the number is
