What is the surface area of the composite figure
shown?
107 square feet
O 172 square feet
O 279 square feet
O 321 square feet

Faces:
Triangles (2): A = 1/2(5)(7)
Rectangles: 2 are 6 by 6; 2 are 5 by 6; 2 are 7 by 5; 1 is
6 by 7

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
