Answer:
vol. of triangular prism = lbh/2
vol. of rectangular prism = 18 of vol. of triangular prism
18x = 18 + 14x
4x = 18
x=4.5 ft
so vol. of rectangular prism = 6 × 4 . 5 × 3 = 81 ftcube
p(the person does not use any facility)= 59/130
Add all the like terms
3b + b = b(3 + 1) = 4b
So, 3b + b + 6 = 4b + 6
