-3(4-3x=9x-12
-12+9x=9x-12
9x-9x=-12+12
X=0

Step-by-step explanation:
To solve question 4, you have to work backwards. Plug 40.82 as C in the formula C = D x 3.14. It would now look like: 40.82 = D x 3.14. Divide 40.82 by 3.14 and you would receive 13 as the diameter. However, we are searching for the radius. The radius is half of the diameter. 13 / 2 is 6.5
To solve question 5, you'll need to use the formula C = D x 3.14. So far, we know D is 6. 6 x 3.14 is 18.84. Yet, we need to find the cost. Each foot costs $12.50, so that's what we multiply to 18.84. In the end, the cost is $235.50.
Answer:
z = -7
Step-by-step explanation:
8-12z=92
-12z = 92-8
-12z = 84
z = 84/-12
z = - 7

Answer:

Step-by-step explanation:
The surface area of right triangular prism is the sum of area of two base triangles and 3 area of side rectangles.
The area of base triangle is

where a is the length of the side of equilateral triangle. In your case, a=6 inches. Thus,

The area of side rectangle is

where h is the height of the rectangle. In your case, h=10 inches. Thus,

Hence, the surface area is
