Solve for u. $$d = 9 \sqrt { u }$$
A) $u = \frac { d } { 9 }$
B) $u = \frac { d ^ { 2 } } { 9 }$
C) $u = \frac { d } { 81 }$
D) $u = \frac { d ^ { 2 } } { 81 }$

Quizplus · Accepted Answer

To solve for $u$, square both sides of the equation to get rid of the square root, resulting in $d^2 = 81u$. Then, divide both sides by 81 to isolate $u$, giving $u = \frac{d^2}{81}$.

Solve for U d=9ud = 9 \sqrt { u }d=9u​ A) u=d9u = \frac { d } { 9 }u=9d​

Solve for U $d = 9 \sqrt { u }$ A) $u = \frac { d } { 9 }$
