What are the solutions to the quadratic equation (5y + 6)2 = 24?

lana [24]

To solve for y, apply the distributive property:
$10y + 12 = 24$
Then, subtract 12 from both sides and you will get:
$10y = 12 \\$
Then solve for y, by dividing both sides by 10.

Your final answer will be y=1.2

$\bf \begin{cases}
\textit{area of a circle}=\pi r^2
\\ \quad \\
circumference=2\pi r
\end{cases}
\\ \quad \\

12.56=\pi r^2\implies \cfrac{12.56}{\pi }=r^2\implies \sqrt{\cfrac{12.56}{\pi }}=\boxed{r}
\\ \quad \\
thus
\\ \quad \\
circumference=2\pi \boxed{r}\implies 2\pi \boxed{\sqrt{\cfrac{12.56}{\pi }}}$
