A triangle with 9 meters,12 meters ,and 15 meters is a triangle because the two sides lower numbers sides add to get a bigger number the the thrid side so I would be a right triangle
The perimeter of a square :
P = 4a (a being the side)
= 4(8)
= 32 in.
First do inside the parenthesis first.
When dividing two exponents subtract them.
15-5 = 10
So w^15 / w^5 becomes w^10
Now you have (w^10)^4
Now multiply the exponents:
10 x 4 = 40
Final answer is w^40
