F(x) = 3x + 2
g(x) = 5x - 10
g(x) - f(x) = (5x - 10) - (3x + 2)
g(x) - f(x) = (5x - 3x) + (-10 - 2)
g(x) - f(x) = 2x - 12
The answer is B.
2(x + 4) = -10 |divide both sides by 2
x + 4 = -5 |subtract 4 from both sides
x = -9
Answer:
162 m²
Step-by-step explanation:
To find the area of this composite solid, we need to find the area of each surface and sum them up.
Formula for finding area is length x width.
Area of each surface:
3 * 2 = 6
9 * 2 = 18
5 * 2 = 10
2 * 2 = 4
8 * 2 = 16
(11-2) * 3 = 27
Considering the fact that each surface appeared twice in the figure, the area of the surface will be calculated as:
(6 + 18 + 10 + 4 + 16 + 27) * 2
= 81 * 2
= 162 m²

We are given
Revenue, g(x) = 2300x+1235, and
expenses, f(x) = 1600x+2385
We know that
profit = Revenue - expenses
=g(x)-f(x)
=2300x+1235 - (1600x+2385)
=2300x+1235 - 1600x - 2385
=2300x- 1600x +1235 -2385
=700x - 1150
