Answer:
78.5
Step-by-step explanation:
πr²
= π×5²
= 25π
= 78.5
Known fact:
- $100 dollars for 8 hours of work --> $100 / 8hrs = $12.50 dollars/hrs
Two hours of work = $12.50 dollars/hr * 2hrs = $25 dollars
Six hours of work = $12.50 dollars/hr * 6hrs = $75
Ten hours of work = $12.50 dollars/hr * 10hrs = $125
fourteen hours of work = $12.50 dollars/hr * 14hrs = $175
Thus the answer is the bottom left choice.
Transposition
Transposition is a method to isolate the variable to one side of the equation and everything else to the other side so that you can solve the equation.
Algebraic equations can be solved using the Law of equations. The Law of equations states that whatever you do on one side of an equation, you must do on the other side as well.

Answer:
the answer for this problem is x^2+2x-15
Step-by-step explanation:
(x+5)(x-3)
x(x-3)+5(x-3)
x^2-3x+5(x-3)
x^2-3x+5x-15
=x^2+2x-15
