Which equation has no solution A.) 4(x+3)+2x=6(x+2) B.) 5+2(3+2x)=x+3(x+1) C.) 5(x+3)+x=4(x+3)+3 D.) 4+6(2+x)=2(3x+8)

B. 5+2(3+2x)=x+3(x+1)

Step-by-step explanation:

Expand the brackets.

5 + 6 + 4x = x + 3x + 3

11 + 4x = 4x + 3

Add -4x and -11 on both sides.

4x - 4x = 3 - 11

0 = -8

There are no solutions.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

the answer is 8/21
