Step-by-step explanation:

1. reflections preserve everything but coordinates, translations do the same. Rotations change the sides coordination, as in the short sides/long sides switch

2. We would need to do a 90 degree rotation to get to the green rectangle, but it would still end up in the other quadrants, with a translation the rectangle would go into the rightful . place.

3. You can do an anticlockwise 90* rotation then translate

Solve the equation 3(2x+2)=3x-15 x=-7 x=-17/3 x=3 x=7

Nady [450]

3(2x+2)=3x-15

mutiply the bracket by 3

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

6x+6= 3x-15

move 3x to the other side

sign changes from +3x to -3x

6x-3x+6= 3x-3x-15

6x-3x+6= -15

3x+6= -15

move +6 to the other side

sign changes from +6 to -6

3x+6-6= -15-6

3x= -21

divide by 3 for both sides

3x/3= -21/3

x= -7

Answer: x= -7
