Question

The base of a triangle is represented by (2x − 6) and the height by (x − 2). Which polynomial expression BEST represents the area of the triangle?

Answer 1

Area of a triangle= $\frac{1}{2} *base*height$
A=$\frac{1}{2} *(2x-6)*(x-2)$
A=$\frac{1}{2} ( 2x^{2} -4x-6x+12)$
A=$x^{2} -2x-3x+6$
A=$x^{2} -5x+6$

Answer 2

x2 - 5x + 6 is the answer. Hope this helps.
