(x - 5)(x^2 + 4x - 2) =
x(x^2 + 4x - 2) - 5(x^2 + 4x - 2) =
x^3 + 4x^2 - 2x - 5x^2 - 20x + 10 =
x^3 - x^2 - 22x + 10 <===
HOW TO SOLVE:
1) use x as a variable
2) the starting equation is:
4x + 3x + 5x = 18
3) add all the like terms on the left side of the equation:
12x = 18
4) Divide by 12 on both sides:
x=1.5
5) Find the lengths of the sides:
- 4x = 4(1.5) = 6
- 3x = 3(1.5) = 4.5
- 5x = 5(1.5) = 7.5
SO, the lengths of the sides of this triangle are: 6, 4.5, and 7.5

Answer:
Step-by-step explanation:
Domain is the x value
Range is the y value
If its a function then that means that your x-value only goes to one y-value
If its not a function then that means that your y-value goes to more than one x-value

Answer:
a. earned: $292.50
b. total: $2,092.50
Step-by-step explanation:
A = 1800 [1 + (0.065 * 2.5)] = 2092.5
A = $2,092.50
To find the amount is earned, subtract the total with how much to started with
2,092 - 1,800 = 292.50
