Serrians triangle has a height of 3x-4 and the base length is 8x+4 what is the area of the triangle

Area of a triangle is base * height : 2

base=8x+4 x=-4/8 x=-1/2

height=3x-4 x=4/3

A=b*h:2

A = (-1/2*4/3) : 2

A = (-4/6) : 2

A = (-4/6) : 2/1 to divide by fractions flip the second and multiply

A=-4/6*1/2

A=-4/12

A=-1/3
