A triangle has one side that measures x, another side that measures 2x, and a third side that measures 5 less than x. The perime
ter is 31 inches. Which equation would you use to find the value of x? Explain your answer
A. x + 2x + x - 5 = 31
B. x + 2x + x + 5 = 31
C. x + 2x - x - 5 = 31
D. x + 2x - x + 5 = 31
1 answer:
1st side = x
2nd side = 2x
3rd side is x-5
so x +2x + x-5 = 31
answer is A

740 m^2
Step-by-step explanation:
I think the answer is 22mn2+66m2n-64 since there are no more like terms
(1/4)x = 2
x = 8 x 3 = 24 feet long
(1/4)x = 1
x = 4 x 3 = 12 feet wide
24ft x 12ft = 288ft^2
