## anonymous one year ago If 5p = -100 + 3Q^2, which of the following could Q possibly be?

1. anonymous

Q = square root of 5 times p minus 100 over 3 Q = square root of 5 times p plus 100 over 3 Q = square root of negative 5 times p plus 100 over 3 Q = square root of negative 5 times p minus 100 over 3

1.add 100 to both sides and then divide by 3 2. take the squareroot

6. anonymous

so that would be q^2 = 100+5p/3

7. anonymous

the sqrt of 100 + 5p/3 = q

8. anonymous

So it would be the second one?

if you write fractions like that, you need to use parentheses! $5p = -100+3Q^2$$5p+100 = -100+100 + 3Q^2$$(5p+100)/3 = Q^2$ $Q = \sqrt{(5p+100)/3}$

$3 Q^2=5P+100$ $Q^2=\frac{ 5P+100 }{ 3 }$ Q=?

100 + 5p/3 is not the same as $\frac{100+5p}{3}$

oh ok thanks you both so much for the help
