Which term can be cancelled out of the expression

Lubov Fominskaja [6]

Answer:

x+3

Step-by-step explanation:

If you factor 5 out of the denominator of the first expression, 5x+15 turns into 5(x+3).

Then, since you have x+3 in the numerator and denominator, it will cancel out.

The steps are shown below:

$\frac{7x}{5x+15} *\frac{x+3}{8} \\\\=\frac{7x}{5(x+3)} *\frac{x+3}{8} \\\\=\frac{7x}{5} *\frac{1}{8} \\\\=\frac{7x}{40}\\$

Ive attached an image that shows an example of simplifying an expression using a the same technique.

What is the area of a 30 degree sector of a circle with area 96 pi meters ^2?

iren2701 [21]

$\bf \textit{area of a circle}\\\\
A=\pi r^2~~
\begin{cases}
r=radius\\
-----\\
A=96\pi 
\end{cases}\implies 96\pi =\pi r^2
\\\\\\
\cfrac{96\underline{\pi }}{\underline{\pi }}=r^2\implies 96=r^2\implies \boxed{\sqrt{96}=r}\\\\
-------------------------------$

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}~~
\begin{cases}
r=radius\\
\theta = angle~in\\
\qquad degrees\\
------\\
\theta =30\\
r=\boxed{\sqrt{96}}
\end{cases}\implies A=\cfrac{(30)(\pi )(\sqrt{96})^2}{360}
\\\\\\
A=\cfrac{(30)(\pi )(96)}{360}\implies A=8\pi$
