9x+6 = 3(3x + 2) distributive property ​

Identity Solution

Step-by-step explanation:

9x+6 = 3(3x + 2)

9x + 6 = 9x + 6

0x = 0

Identity Solution: Infinite; solution set {all real numbers}

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
