Answer:
y = 7
Step-by-step explanation:
The similarity statement 
tells you which vertex from the first polygon corresponds to which vertex from the second polygon.
A is paired with W, B is paired with X, C is paired with Y, D is paired with Z.
The expression <em>y</em> + 2 is placed along side WZ which corresponds to side AD in the first polygon.
Now locate two sides, one from each polygon, that are labeled with just <u>numbers</u>. That way, you'll be able to tell what the proportion is between the two shapes.
AB and WX correspond and are labeled 5 and 3, respectively.
Now you can write a proportion:
Use the Means-Extremes Property ("cross multiply").
D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1

Step-by-step explanation:
24 has a lot of factors
1 2 3 4 6 8 12 and itself.
It is easy to talk about fraction of a day. Like work is 8 hours which is 1/3 of a day. So is sleep. So is recreation. The description of how long it would take to walk 4 miles is about 1 hour
23 is prime. It has no other number that could divide into parts of a day. There's 1 and there's 23 and that's all. How would you say 1/3 of a day and have it meaningful, particularly if you didn't know much about fractions?
25 is nearly as bad, but not quite. It does suffer from not being about to have parts of a day evenly described as 1/3 or a day or 1/6 of a day.
Answer is C.
3x and 4x² are not like terms, as their exponents do not share the same power (3x has a power of 1, 4x² has a power of 2)
