Question

Which expression shows the result of applying the distributive property to 3(15x−17) ?

3/5x−3/7

−3/5x−3/7

3/5x+3/7

−3/5x+3/7

Answer 1

You just multiply 3 by both 15x and -17. None of these choices are correct. The only correct application would be A.

Answer 2

Answer:

$\frac{3}{5}x-\frac{3}{7}$  

Step-by-step explanation:

we have

$3(\frac{1}{5}x-\frac{1}{7})$

Applying the distributive property

$3(\frac{1}{5}x-\frac{1}{7})=3(\frac{1}{5}x)-3(\frac{1}{7})\\ \\=\frac{3}{5}x-\frac{3}{7}$
