First term = 2(1) - 3 = 2 - 3 = -1
B) No, because opposite sides are not parallel
Step-by-step explanation:
Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;
Parallel sides to be : WX // YZ and XY // WZ
Additionally, we know parallel sides have equal gradient thus;
The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ
However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.

My method is on a) you would just subtract 12 and 7 which is 5. You can do the rest and then when you get all the answers put them from smallest to largest
6(1.15) + 3.75 + 7.45 + 13(1.15) + 3(37) =
6.90 + 3.75 + 7.45 + 14.95 + 111 =
144.05 <== total bill
