Which statement best explains the equation x+3+3x+7=180 can be used to solve for ?

The answer is I.)

Step-by-step explanation:

"If parallel lines are cut by a transversal, corresponding angles are congruent."  

This means that < M = x+3, then < A also = x+3,

and < H = 3x+7, so < T= 3x+7

I hope this helps :)

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
