Answer:
If the lines BC and DE are parallel, the value of c is c=-2
Step-by-step explanation:
We are given line segment BC with end points B(2, 2) and C(9,6) and line segment DE with endpoints D(c, -7) and E(5, -3).
Using slope formula: 
we can find point c
When 2 lines are parallel there slope is same.
So, Slope of line BC =Slope of Line DE
We have:
Putting values and finding c
So, If the lines BC and DE are parallel, the value of c is c=-2

Answer: 17 inches</h3>
===============================
Rule: All four sides of a rhombus are the same length
So AB = BC
Use this to solve for x
AB = BC
3x+2 = x+12
3x-x = 12-2
2x = 10
x = 5
If x = 5, then
AB = 3*x+2 = 3*5+2 = 15+2 = 17
and
BC = x+12 = 5+12 = 17
Both sides are 17 as expected, so the proper x value is confirmed.
So DC is also 17 since AB = DC
C= pi•diameter. If the dinner plate's diameter is 7 inches, then multiply 7 times pi, 3.14. 7•3.14= 21.98. So, the answer for the first question is B, 22. :)
For the second question, it is asking for the answer in terms of pi. Since the diameter is 6, divide 6 by 2 to get the radius. (A=pi•radius squared) 6 divided by 2 is 3. Now, square 3. which gives you 9. Since the answer has to be in terms of pi, the answer is B. ;)
