1. satellite73 Group Title

is it $$-4\sqrt{x+9}=20$$ or is it $-4\sqrt{x}+9=20$?

2. kaleighdunn Group Title

the first one

3. satellite73 Group Title

then there is no answer, because the left hand side $$-4\sqrt{x+9}$$ is negative, but the right hand side $$20$$ is positive

4. satellite73 Group Title

$$\sqrt{a}$$ is always greater than or equal to zero, so when you multiply by $$-4$$ the term will be less than or equal to zero, and it cannot equal a positive number
