The perimeter of the rectangle ABCD:
P = 2AD + 2AB
We have AD = 4z and AB = 5z + 2 and perimeter = 220 units. Substitute:
2(4z) + 2(5z + 2) = 220 <em>use distributive property</em>
8z + (2)(5z) + (2)(2) = 220
8z + 10z + 4 = 220 <em>subtract 4 from both sides</em>
18z = 216 <em>divide both sides by 18</em>
z = 12 units
Substitute to AD:
AD = 4(12) = 48
<h3>Answer: AD = 48 units.</h3>
D. 40 degrees because angle 8 is the same as angle 4. angle 4 is 50 degrees

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values.
