Answer:
104
Step-by-step explanation:
Any expression multiplied by 0 equals 0
when adding or subtracting 0, the quantity doesn't change
Part (a)
<h3>Answer: y1 and y3 are perpendicular</h3>
This is because the two slopes 2 and -1/2 multiply to -1. Perpendicular slopes multiply to -1 assuming neither line is vertical or horizontal.
=====================================================
Part (b)
Graph each line to see where they cross. The three points of intersection are
(0,4)
(2,-2)
(4,2)
The order of the points doesn't matter.
You could also form three systems of equations pairing up the equations, and solving each system. That way you can find the points of intersection. Graphing may be a better and faster route in my opinion. See the diagram below.

Determine the length of AB
Because A'B'C'D is a dilation of ABCD, then the following relationship must exist:

Substitute values for A'B', B'C' and BC

Express the ratio as fractions:

Multiply through by 14
