Answer:Just calculate this:

A) 2(3m + 5) = 6m + 10 - incorrect

B) -2(5 - 3m) = -10 + 6m - could be correct

C) 2(3m - 10) = 63 - 20 - incorrect

So the correct answer has to be B: -10 + 6m is the same as 6m - 10 hopes this help

The coordinates of trapezoid ABCD are A(−4, 3), B(2, 3), C(4, −1) and D(−4, −1). A line segment runs through the trapezoid with

madam [21]

The distance from point Y to the y-axis is 4 units and the distance from point Z to the y-axis is 3 units, then the lelgth of the segment YZ is 4+3=7 units.
If a scale factor is 3, then the length of Y'Z' will be 7·3=21 units.

P.S. In the added picture you can see trapezoid ABCD that was dilated by a scale factor 3 about the origin. This may help to understand that all linear values after dilation become multiplied by scale factor.
