So,
187 divided by 7
187/7
Mixed: 26 5/7
Decimal: 26.714285 (there is a vinculum over the "714285")
the length of the bottom side is 17-3 = 10
to be a square all sides need to be 10 units.
A(7,13)
B (17,13)
7 yd > 1 ft, 25 ft > 38 in. idk about that 3 ft there
(24-x)/8=x/6
or 24-x=4x/3
24(3)-3x=4x
24(3)=7x
24(3)/7=x
