ANSWER: 
</h2><h2>
EXPLANATION:</h2>

To write as power, you will see how many times you multiply the number 10.

Since it was multiplied 7 times, you would write it like this.

Hope this helps!

L =
- W
P = 2L + 2W = 2(L + W) → ( take out common factor of 2)
divide both sides by 2
= L + W
subtract W from both sides
- W = L
