Make m the subject of the formula. r=5m^2-n

The answer is

Step-by-step explanation:

To make m the subject send n to the left side of the equation

That's

Divide both sides by 5

We have

Find the square root of both sides to make m stand alone

That's

We have the final answer as

Hope this helps you

Step-by-step explanation:

r = 5m² - n

Add n to both sides

r + n = 5m² - n +n

r + n = 5m²

Divide both sides by 5

(r+n)/5 = 5m²/5

(r + n)/5 = m²

Take square root ,

inverse operation of addition
