Question

Which term can be cancelled out of the expression​

Answer 1

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:

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