Triangle XYZ is translated by the rule (x + 3, y - 2) and then reflected over the x-axis to create the triangle X'Y'Z'. Which statement is true?
OA. A X'Y'Z' is a 90° clockwise rotation of AXYZ.
OB. A XYZ is similar to and congruent to A X'Y'Z'.
OC. AX'Y'Z' is a 180° clockwise rotation of A XYZ.
O D. AXYZ is similar, but not congruent to AX'Y'Z'.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
