Which of the equations below has no solution? Due soon need help

 Pretty sure its B I see non of the same numbers that can fit it.

Here's why:

The 4 and 8 on the left side combine to 12. The 5x and -3x on the right hand side combine to 2x.

This means the equation for choice D becomes 2x+12 = 2x-12

From here, subtract 2x from both sides. Doing so will cancel each copy of 2x and the x terms go away entirely. We're left with 12 = -12 which is a false statement since we don't have the same number on both sides. We have a contradiction instead, so there are no solutions here.

No matter what we replace x with in equation D, it will always be false.

If you graphed y = 2x+12 and y = 2x-12, you would find that the lines are parallel. Parallel lines never intersect. Intersection points are solution points, so this is a visual way to see that we don't have any solutions.

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

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