I believe X = 8

Step-by-step explanation:

you would use the equation D + C = B or

48 + 5x + 11 = 11x + 11

then subtract 11 from each side leaving

48 + 5x = 11x

then you would subtract 5x from each side, leading to

48 = 6x

48 ÷ 6 = <u>8</u>

Base of a prism is a right triangle with legs 3 feet and 4 feet. The height is 13 feet , what is the volume?
julsineya [31]

Answer:

Triangular prisms

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h
