Answer:
The volume of the prism is x^3 + 16x^2 + 63x
Step-by-step explanation:
Mathematically, the volume of the prism is the area of the base multiplied by the height of the prism
The area of the base is l * w
= (x + 7)(x + 9) = x^2 + 7x + 9x + 63 = x^2 + 16x + 63
The volume is now; x(x^2 + 16x + 63)= x^3 + 16x^2 + 63x
when r = c is the break even point.
since r = 14x and c = 12x + 36000, then the break even point is when 14x = 12x + 36000
subtract 12x from both sides of this equation to get 14x - 12x = 36000.
combine like terms to get 2x = 36000.
divide both sides of this equation by 2 to get x = 18000.
that'a our answer.
the revenue will be equal to the cost when 18000 units are sold.
revenue = 14 * 18000 = 252000.
cost = 12 * 18000 + 36000 = 252000.
Answer:
The expression = -75
Step-by-step explanation:
Evaluate: Enter a number for each variable.
−x2+7(y+2)−1
x=
5
y=
-9
Evaluate for x=5,y=−9
−52+7(−9+2)−1
−52+7(−9+2)−1
=−75
We can apply the following properties of radicals:
