Luke has some boxes that are all cubes of the same size.
Scrat [10]

Answer:

The height of a pile of 5 equal sized boxes is 95cm.

Step-by-step explanation:

We know that 1 pile of 4 is 76 cm. All we have to is divide this by 4 to find how tall one box is.

76/4 = 19.

This means that one box is 19 cm tall.

Now we will add 19cm to 76cm.

19 + 76 = 95

The height of a pile of 5 equal sized boxes is 95cm.

Simplify the expression<br><br>cot^2x - cot^2x cos^2x
andrew-mc [135]
Cot^2x - cot^2x cos^2x
= cot^2x - {(cot^2x)(cos^2x)}
= cot^2x { 1 - cos^2x }
= cot^2x { sin^2x }
= (cos^2x/sin^2x) { sin^2x }
= cos^2x
