The trapezoid below is formed from two triangles and a rectangle. What is the area of the trapezoid? 9 cm
3 cm
6 cm
3 cm
A 81 cm 2
B 54 cm2
C 108 cm2
D 67.5 cm 2

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

a: inscribed angles
