Hi!
length = l = 2 * width = 2 * w
Area = l * w = l * 2 * l = 2 * l^2
2 * l^2 = 72
l^2 = 72/2 = 36
l = square root of 36
l = 6
l = 2 * w => w = l/2 = 6/2 = 3
Perimeter = 2 * l + 2 * w = 2 * 6 + 2 * 3 = 12 + 6 = 18 feet
Hope this helps!

Answer:
720,080 = 700,000 + 20,000 + 80 =
7 * 100000 + 2 * 10000 + 0 * 1000 + 0*100 + 8*10 + 0*1 =
7 * 10^5 + 2 * 10^4 + 0 * 10^3 + 0* 10^2 + 8 * 10

Find x
5x-7=13x+17
minus 5x
-7=8x+17
minus 17
-24=8x
divide 8
-3=x
subsitute
6(x-4)
6(-3-4)
6(-7)
-42
6(x-4) is -42
