Question

The three steps shown below were used to find anexpression equivalent to 3(15x – 30y) + 10x.1. ?2. 16x - 12y3. 4(4x – 3y)Which expression could be used as Step 1?A. }(25x – 30y)B. 6x – 12y + 10xC. 6x – 30y + 10xD. 15(x – 2y) + 10x

Answer 1

Step one could probably have been the result of multiplying 2/5 by the expression inside parenthesis:

`(2)/(5)\cdot(15x-30y)+10x=6x-12y+10x`

This would be option B
