Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x2−2x−8=0
Step 2: Factor left side of equation.
(x+2)(x−4)=0
Step 3: Set factors equal to 0.
x+2=0 or x−4=0
x=−2 or x=4

The correct answer would be A, because 160/10 is getting you your unit rate, or the amount Sarah spent every week.
Answer:
x=13
Step-by-step explanation:
The right side is a right triangle
The base is 1/2 of the bottom or 5
The height is 12 and the hypotenuse is x
We can use the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +12^2=x^2
25+144 = x^2
169=x^2
Take the square root of each side
sqrt(169) = sqrt(x^2)
13=x
