The answer is -6x^3+11x^2+19
1 piece of pipe ⇒ 3/4 feet
How many pieces? = 27 feet
27 × 1 ÷ 3/4 = 27 × 4/3 = 36 pieces.
Answer: 1.25 or 5/4
Steps:
Move the -3x to the other side by adding it which gives you 4x=5. Then divide by 4 to have the x alone which gives you the answer. Hopes this helps :)
This is the distributive property of multiplication
((5x5)/2)x2=50 square ft
(8x5)x2= 80 square ft
8x7= 56 square ft
50+80+56=186 square ft
D) 186 square ft
