Question 825682: The two non-parallel sides of a trapezoid are equal and the perimeter is 18 units. the shorter of the two parallel sides is four less than one of the equal sides and the longest sides is 5 more than one of the equal sides. Find the length of each side

Not too tough if you draw the trapezoid and label the sides according to your description.

Not showing the figure, but stating expressions for each side:
Two non-parallel opposite sides, each x.
Short parallel side, x-4.
Long parallel side, x+5.

The perimeter is given as 18, so setup x%2Bx%2B%28x-4%29%2B%28x%2B5%29=18;
.
2x%2Bx-4%2Bx%2B5=18
4x%2B1=18
4x=17
highlight_green%28x=17%2F4%29, use this then to find each of the parallel side length.
