Answer:
Length of side XY needed
Step-by-step explanation:
Since Triangle ABC is similar to triangle XYZ . (They are not congruent)
Thus,
= .
Here, AB and AC are given but length of XY is not given so we can't solve it to find the length of side YZ.
So, Given information is insufficient to calculate YZ
2x^2 - 2 is the answer for this equation, hope this helps you.

Answer:
Step-by-step explanation:
m = number of minutes
$ 8 monthly fee + 19 cents per minute
the expression for this is : 8 + 0.19m
$ 25 monthly fee and 14 cents per minute
the expression for this is : 25 + 0.14m
to find out when they will be equal, just set them equal to each other and solve for m, the number of minutes
8 + 0.19m = 25 + 0.14m .....subtract 0.14m from both sides
8 + 0.19m - 0.14m = 25......subtract 8 from both sides
0.19m - 0.14m = 25 - 8.....combine like terms
0.05m = 17...divide both sides by 0.05
m = 17 / 0.05
m = 340 <==== they are both the same at 340 minutes
Distribute the terms:
14x-56=77x
Get the variable to one side (subtract 14x from each side):
-56=63x
Divide both sides by 63:
-8/9=x
x=-8/9
