30% decrease.
120-90 = 30
1000 since the 348 in 1348 is closer to 1000 than 2000
This is a false statement.
When you are solving using square roots, you need to be aware that answers can be both positive and negative. When we solve this, you see there are two possible answers.
x^2 - 9 = 0
x^2 = 9
x = +/- 3
While 3 is an answer, so is -3. If we square either of those numbers, we get 9, which will satisfy the equation.
It’s probably 9 I’m not that sure
