Please can someone help me with this question

r = -

Step-by-step explanation:

Rewrite the equation as  = m

Remove the radical on the left side of the equation by squaring both sides of the equation.

( = m^2

Then, you simplify each of the equation.

Rewrite: ( as

Remove any parentheses if needed.

Solve for r.

Multiply each term by r and simplify."

Multiply both sides of the equation by  5.

6a+r= m^2r⋅(5)

Remove parentheses.

Move 5   to the left of (m ^2)  r

6a+r=5m^2)r

Subtract  5m^2)r  from both sides of the equation.

6a+r-5m^2)r=0

Subtract  6a  from both sides of the equation.

r-5m^2)r=-6a

Factor  r out of  r-5m^2)r  

r(1-5m^2)=-6a

Divide each term by 1-5m^2 and simplify.

r = -

There you go, hope this helps!
