How do you do inequalities

fgiga [73]

So some quick tips for inequalities:

(e.g. 2>-5x>25)
-2/5 <x < -5

I hope that this has helped!

Which expression is equivalent to StartRoot 120 x EndRoot?.

Irina-Kira [14]

Here for 120, the expression for the start root and end root is given

$\sqrt{120} =2\sqrt{30}$

<h3>What will be the expression for start root and enroot of 120?</h3>

Here we need to find $\sqrt{120}$

By simplifying the given expression, we get:

$120=2\times2\times2\times3\times5$

$120=(2^{2} )\times3\times5$

by taking square roots on both sides we get

$\sqrt{120} =2\sqrt{30}$

Thus for 120, the expression for the start root and end root is given $\sqrt{120} =2\sqrt{30}$
