A triangle has base 2x+1 and height 6x-3. What value of x would give an area of 240m2?

The values of x which would give an area of 240m² would be:

Step-by-step explanation:

Given

The base of triangle b = 2x+1

The height of triangle h = 6x-3

The Area of the triangle A = 240 m²

The Area of the triangle has the formula

A = 1/2 × b × h

substituting b = 2x+1, h = 6x-3 and A = 240

Subtract 480 from both sides

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

solving

Divide both sides by 2

also solving

Divide both sides by 2

Therefore, the values of x which would give an area of 240m² would be:

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
