Answer:
6x^2 + 2x - 5 (Option C)
Step-by-step explanation:
1. First, add 4x^2 and 2x^2 together (which is 6x^2). You can figure this out by adding 4 and 2.
2. Second, add -5x and 7x (which is 2x)
3. Lastly, subtract 3 and 8, which is -5
WHY DOES THE ANSWER HAVE A NEGATIVE 5?
The equation looks like this: +3 + -8
You are adding 3 to -8, which is the same as subtracting positive 3 and positive 8 (positive times a negative is a negative or a minus sign)

easyyyyyyy
Step-by-step explanation:
table J!
9(n+3)=7n-3
1) distribute 9 into (n+3)
9n+27=7n-3
2) subtract 7n on both sides
2n+27=-3
3) subtract 27 on both sides
2n=-30
4) divide by 2
n=-15
