v = - 5
distribute right side of equation and simplify
2v + 18 = 16 - 4v - 28
2v + 18 = - 12 - 4v ( add 4v to both sides )
6v + 18 = - 12 ( subtract 18 from both sides )
6v = - 30 ( divide both sides by 6 )
v =
= - 5
Answer:
Volume of rectangular prism:
V1 = base x height = 4 x 6 x 12 = 288 ft3
Volume of triangular prism:
V2 = base x height = 4 x (6/2) x 6 = 72 ft3
Volume of composite prism:
V= V1 + V2 = 288 + 72 = 360 ft3
Hope this helps!

Answer:
3.5
Step-by-step explanation:
[(3 x 2) - 2 x 1.25] = [6 - 2 x 1.25]
= [6 - 2.5]
= 3.5
