Solve for x. 3(x + 2) = 12 a. x = 2 b. x = 3 1/3 c. x = 4 2/3 d. x = 6

Equation

3(x + 2) = 12


Open the bracket

3x + 6 = 12


Subtract 6 from both sides

3x + 6 - 6 = 12 - 6
3x = 6


Divide by 3 on both sides

3x ÷ 3 = 6 ÷ 3
x = 2


x = 2 (Answer A)

 

3(x+2)=12
3x+6=12
3x=12-6
3x=6
x=2

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
