Answer:
510000
Step-by-step explanation:
15 - x = 2(x + 3)
15 - x = 2x + 6
15 = 3x + 6
9 = 3x
3 = x
x = 3
We have the formula A = (h x b) / 2, where A is the area of the triangle, h is the height of the triangle, b is the base of the triangle;
So, 32 =(8 x b) / 2;
Then, 64 = 8 x b;
b = 64 ÷ 8;
b = 8 inches;
25,000 x .04 = 1000 a year......
so 7,000 after 7 years
So, in 7 years she'll be making 32,000 a year
Since the cross section is constrained to be perpendicular to the base, the shape of it is constrained to be a ...
Rectangle
_____
That rectangle may be a square, but is not required to be.
