What is the answer to this somebody!!!
Galina-37 [17]

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}
