Answer:
420.25
Step-by-step explanation:
If the perimeter is 82, each side is 20.5. Then you do 20.5 x 20.5 to get 420.25.
(2x)/3 = 4
first multiply both sides by 3 to clear the fraction
2x = 12
next divide both sides by 2
x = 6
Do you have an equation to go with that?
Find the quotient: (25c^4 + 20c^3) ÷ 5c5c^3+4c^2.
