Question

What is the answer to this somebody!!!

Answer 1

So with this, you'll be using a proportion to solve it. And here's what your equation will look like:

$\frac{30}{x} =\frac{x}{24}$

Firstly, you'll need to cross-multiply. Your equation will look like this: $720=x^2$

For this, all you need to do is square root, and your answer is $\sqrt{720} =x$, however this answer can be simplified further.

$\sqrt{720} =\sqrt{30*24} =\sqrt{5*6*6*4}=\sqrt{5*3*2*3*2*2*2} =4*3\sqrt{5} =12\sqrt{5}$

In short, your answer is $12\sqrt{5}$
