Answer:
(2) a rotation by
about the intersection of the lines creating the vertical angles.
Step-by-step explanation:
Rigid motion are a set of transformation procedure to change the dimension, orientation or size of a given figure or shape. It involves rotation, translation, reflection and dilation.
Vertical angles are formed when two straight lines intersect to form angles. But two opposite angles called vertical angles are equal. To prove that vertical angles are equal; a rotation by
about the intersection of the lines creating the vertical angles is required.

Answer:
Equivalent expression of
is, 
Step-by-step explanation:
The distributive property says that:

Given the expression: 
Apply the distributive property:

Simplify:

Therefore, the equivalent expression of
is, 
You have

So, we have to compute g(7) and feed it as input to f(x). We have

17^2, pi, 8/3^2 that's the answer
