A cabinet was filled with 4 layers of 1-foot cubes. Each layer has 4 rows, with 4 cubes in each row. What is volume of the cabinet?

if you mean

then it's c. 8, -7/3

but if you mean

then it is

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
