4 * side^2 = diagonal1 ^2 + diagonal2 ^2
4 * side^2 = 12^2 + 16^2
4 * side^2 = 144 + 256
4 * side^2 = 400
side^2 = 100
side = 10
So the perimeter = 4*10 = 40
A represents the lower number in the group.
The answer is.................
A!!!!!!!!!!!!
Day 1:
5 haircuts @ $25.75 = $128.75
3 Color treatments @ $40.50= $121.5
Total =$250.25 per day
$250.25 x 6 days =$1,501.50
Does is have a total perimeter of the triangle? If not, the closest you can get is by simplifying.
2x+3x-1+4x+5
9x+4
