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

Answer:
x > 
Step-by-step explanation:

Add 3 and 1 to get 4.

Use the distributive property to multiply 5 by 9−x.

Subtract 45/5 from both sides.

Since 44/4 and 45/4 have the same denominator, subtract them by subtracting their numerators.

Multiply both sides by -4/5, the reciprocal of -5/4. Since -5/4 is negative, the inequality direction is changed.

Multiply -1/4 times -4/5 by multiplying numerator times numerator and denominator times denominator.
