X=line straight across y=vertical line
Answer:

Step-by-step explanation:
The two given triangles, triangle (BDE) and triangle (BAC) share the angle (<B) in common. Moreover, their bases, line (DE), and line (AC) are parallel, this means that through the corresponding angles postulate, angles (<BDE) and (<BAC) are congrunet. Moreover, angles (<BED) and (<BCA) are also congruent. Thus, triangles (BDE) and (BAC) are similar through angle-angle similarity.
The ratio between the corresponding sides of similar triangles is the same. Therefore, one can form the following equation,
.

Answer:
<h2>x = 22 and y = 24</h2>
Step-by-step explanation:

Answer: (x+9) (x+1)^2
if it has multiplicity 1 there is one of them
if it has multiplicity 2 there are two of them (or it is squared)
degree 3 means there are three factors
A is 36
b is 8.5
c is 2.3 (not sure)
d is -6
e is 9
f is 1.8
