40x - 24 - 33x - 77 = 102
40x - 33x = 102 + 24 + 77
7x = 203
x = 29
2*(x-5) = -33, so x-5 = -16.5, so x = -11.5
This is assuming that "the difference between a and b" is a-b, which seems to be the accepted interpretation.
A(area) = b(base) * h(height)
A = 56 * 157
A = 8,792 mi^2
It would be 63135 because that is the highest number you can multiply it into
Prime for 2 digit odd number: 13 , 11 , 17, etc
Odd number that is composite: 39, 25, 15, etc
Hope this helps
