The technology company asks the general contractor to lay gravel on the ground in the area between the warehouse and the fence. Which of the following situations best models the area that the gravel will cover? A = (6 x feet)(6 x feet) - (15 x feet)(8 x feet) A = 84 x2 feet 2 A = (15 x feet)(8 x feet) - (6 x feet)(6 x feet) None of the above.

Step-by-step explanation:

To model the minimum cost to completely cover the ground between the warehouse and the fence with gravel, find the difference between the number of bags of gravel, G, and the cost per bag, $22.

-To model the minimum cost to completely cover the ground between the warehouse and the fence with gravel, find the sum of the number of bags of gravel, G, and the cost per bag, $22.

-To model the minimum cost to completely cover the ground between the warehouse and the fence with gravel, find the product of the number of bags of gravel, G, and the cost per bag, $22.--None of the above.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
