Help, i know the answer but i don’t know how to do the work

Answer:

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying each radical before combining them.

$\sqrt{45t}$

= $\sqrt{9(5t)}$

= $\sqrt{9}$ × $\sqrt{5t}$ = 3 $\sqrt{5t}$

-----------------------------------------------------------------------------

$\sqrt{125t}$

= $\sqrt{25(5t)}$

= $\sqrt{25}$ × $\sqrt{5t}$ = 5 $\sqrt{5t}$

---------------------------------------------------------------------------

Hence

2(3 $\sqrt{5t}$ ) - 3(5 $\sqrt{5t}$

= 6 $\sqrt{5t}$ - 15 $\sqrt{5t}$

= - 9 $\sqrt{5t}$ → C

Help!!! The graph represents (x , y)- pairs that make the equation y = 2x true?

To figure it out u plug in ur x value then multiply it by 2 to get ur y value. So if u had a value of 1 for ur x value ur y value would be 2

Someone help me I don’t understand the circumference C=2TTr

Irina-Kira [14]

You are being asked to make π the subject in

$C=2πr \:$

So divide both sides of the equation by
$2r$

That is

$\frac{ C}{2r} = \frac{2πr}{2r}$
The you have
$\frac{ C}{2r} = \pi$

or

$\pi = \frac{ C}{2r}$

I hope this is helpful?
