The sum of the numbers is 20 10+10=20 20/2=10
You can use (-25,-5) it fits the equation and it’s in the solution set
Answer:
A. 12
Step-by-step explanation:
Selecting B, C, or D would create a difference of perfect squares since each of these numbers are perfect squares. Additional factoring would then be needed.

But selecting 12 gives
which cannot be factored. It is factored completely.
x=11
x is equal to 11 because you subtract 4x from both sides and then add 8 to both sides where you are left with 2x=22. After dividing by 2, you get x=11
