2x+3(x-2)-3(x-6)
You would first distribute.
So:
2x+3x-6-3x+18
Then you would combine like terms, like so:
2x+3x-3x= 2x
-6+18= 12
So it'd be:
2x + 12
Which is answer choice A

Answer:
4(x + 5)(x - 3)
Step-by-step explanation:
Given
4x² + 8x - 60 ← factor out 4 from each term
= 4(x² + 2x - 15) ← factor the quadratic
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
+ 5 × - 3 = - 15 and + 5 - 3 = + 2, then
x² + 2x - 15 = (x + 5)(x - 3)
Then
4x² + 8x - 60 = 4(x + 5)(x - 3) ← in factored form
Answer:
(n-2) × 180°
Step-by-step explanation:
Sum of interior angles for a polygon = (n-2) × 180°

you have found is yourself!
Since -6 +6 can be rearranged to 6-6 using the communicative property, we get 6-6 =0 . In addition, -120+(-6) is essentially having -120+ 1*(-6), and 1 times a number is simply that number, so we have -120-6=-126
