ruslelena [56]

Step-by-step explanation:

Simplify the left side:

5x - 20 = 3x + 4

Move all terms containing x to the left side of the equation:

2x - 20 = 4

Move all terms not containing x to the right side of the equation:

2x = 24

Divide each term by 2 and simplify:

x = 12

Geometry help needed.

Margaret [11]

A'B'C' is larger than ABC, so the scale factor would be a whole number, scale factor of 2.

A'B'C'is also a morrir image of ABC, notice on ABC A is on the left and B is on the right, but on A'B'C', B" is on the left and A' is on the right.

This means it was reflected across the Y axis.

The first answer is the correct one.
