1)Given a triangle that has a base of five less than triple the height. The height is 2x+6. Part A: Determine the expression that represents the area of the triangle Part B: Evaluate the expression above to determine the area to determine the area of the triangle when x=5.

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!

y/x of point b= y/x of point a
