first step to remove brackets
here write them in serial order,
=5x²+3x+4+5x²+5x-1
=5x²+5x²+3x+5x+4-1
=10x²+8x-3
A, 2 since side a is xroot 3 and side b is just the x
Perimeter is all the way around and area is l x w
So 5 x 2 would be 10.....and 5 + 5 + 2 + 2 = 14
So the dimenstions are 5 x 2
Answer:
81 cubic feet of wood
Step-by-step explanation:
Divide it into 5 sections, each 3 feet long because it is 15 feet long.
(1*3*3) + (2*3*3) + (3*3*3) + (2*3*3) + (1*3*3) =
9 + 18 + 27 + 18 + 9 = 81
