HELP ME PlZ bc this is an important quiz

B

Step-by-step explanation:

First, we take the squareroot of both sides. We get the equation "x+3 = +-11" We can separate this equation into TWO equations like so:

x+3=11  --> x=8

x+3=-11 --> x=-14

These both are valid answers to the original equation.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
