Both terms have a 
in common, so we can pull it out. The factored form will be times whatever is left after pulling it out.
In the first term, we will have just 8 left since everything else in the term is factored out.
The second term has a
left. Notice that both of these terms no longer have a negative sign since the negative was factored out.
The answer is
In the first term, we will have just 8 left since everything else in the term is factored out.
The second term has a
The answer is
(AAA) Corresponding angles are congruent.
Therefore, the sides of the triangles are proportional:
cross multiply
use distributive property
subtract 100 from both sides
divide both sides by 100

(SAS)
If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
Therefore we have the equation:
The perimeter of △PQR:
Substitute the value of y to the expression:
