Answer: choice 1 and 6
Step-by-step explanation:
just plug in 9 for every X making sure they equal each other.


Cancel out the denominators.
(x+5)² + 18 = -30
(x+5)² = -30 - 18
(x+5)² = -48
The equation is impossible, we have a negative number.
There isn't a number that squared gives a negative number (the square is always positive).
√(x+5)² = +/- √-48
x+5 = +/- √-48
IMPOSSIBLE
You can write the result in imaginary numbers
x+5=+/- 4i√3
The answer would be C because they say if 3 new students arrived each year.
X=10
12x-1=12+10x+7
2x=20
X=10
True, -4 seems bigger because 4 is bigger than 3 but it's negative and is further away from 0
