Answer:

-16=-16

Step-by-step explanation:

You would first do (-4-2) which would be (-6), after you would multiply (-6) by 4 which comes out to be -24, after you would add 3 which would look like this -24+3 but since its a negative it would come out to be -21 then you would do the same thing with 5, it would look like this -21 + 5 but since its negative it would be -16. I hope this helped :)

A cube has a side length of 8 inches.

Kazeer [188]

The answers are $8^{3}$ and 8 · 8 · 8

Explanation:

The volume of a cube or space a cube occupies is calculated by multiplying the length, height, and width. Additionally, because in a cube all sides are equal in length, the formula for volume is V= $s^{3}$ . According to this, if the side length is 8 inches the volume can be represented as $V = 8^{3}$ or V= 8 · 8 · 8 because the symbol · represents multiplication. Also, this can be solved as V = 512 cubic inches. This makes the following options correct: $8^{3}$ and 8 · 8 · 8.
