Answer:

\frac{2x}{x+7}

Step-by-step explanation:

we have

(\frac{x-3}{x+7})(\frac{2x}{x-3})

When multiply two fractions:

Multiply the numerators of the fractions to get the new numerator.

Multiply the denominators of the fractions to get the new denominator

so

(\frac{x-3}{x+7})(\frac{2x}{x-3})=\frac{(x-3)(2x)}{(x+7)(x-3)}

(x-3) cancels out

\frac{2x}{x+7}

Which transformation shows a reflection of ADEF? ​
antoniya [11.8K]

Answer: B or the second choice

Step-by-step explanation:

well for triangle DEF since E is on the top left, it should be on the bottom right. While F was on the bottom right, it would be on the top left where E originally was. The angles inside has the same situation with E and F, however D stills stays at the top because when reflected like a mirror, D stays at the top. Sorry it’s long and hope this helps!
