Step-by-step explanation:
Answer:
-3x^2-15x-30
Step-by-step explanation:
Let's simplify step-by-step.
−3(x+3)2−3+3x
Distribute:
=−3x2+−18x+−27+−3+3x
Combine Like Terms:
=−3x2+−18x+−27+−3+3x
=(−3x2)+(−18x+3x)+(−27+−3)
=−3x2+−15x+−30
The cost for the contractor to have all the dirt hauled away for a foundation of 12 feet long, 9 feet wide and 6 feet deep is $720
<h3>Volume of rectangular prism</h3>
volume of a rectangular prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
l = 12 ft
w = 9 ft
h = 6 ft
volume of the foundation = 12 × 9 × 6
volume of the foundation = 648 ft³
Therefore, the contractor pays $180 per load for the trucks remove the dirt.
648 cubic feet = 24 cubic yard
6 cubic yards = 1 truck load
24 cubic yard =
cross multiply
number of truck load = 24 / 6 = 4 truck loads
Hence,
1 truck load = $180
4 truck load =?
cross multiply
cost = 4 × 180 = $720
