First, move all the terms to one side
x^2+4x-4-8=0
Then, simplify.
x^2+4x-12=0
After that, factor. Ask yourself: Which two numbers add up to 4 and multiply to -12? That would be -2 and 6. Then, rewrite the expression.
(x-2)(x+6)=0
Lastly, solve for x.
x=2, -6
Your final answer would be x = -6 or x = 2

Consider best strategy to solve the problem. If 9 inches are equal to 27 feet on a map how many feet are equal to three inches

Evgen [1.6K]

Answer:

Step-by-step explanation:

If 9 inches equal 27 what you would do is divide in order to find how much feet would be in 1 inch. So:

9/27= 3 feet

Then to find how much feet are equal to 3 inches you just multiply that by 3. So your answer is 9 feet.

Overall the work should look like

9 inches= 27 feet

9/9 inches= 27/9 feet

1 inch = 3 feet

3 inches x 3 feet

= 9
