The base of the right triangular prism is a right triangle with legs that measure 5 cm and 8 cm. If the height of the prism is 12 cm, what is the volume, V, of the prism?

11

step-by-step explanation:

32.50-7.50=25

225/25=11

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

- (2, -7)

- lines r and s and lines t and u must be parallel

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
