(2+y)^3?
= ((2+y)x(2+y))x(2+y)
= (4+4y+y2) x (2+y)
= 8 + 8y + 2y2 + 4y + 4y2 + y3
= y3 + 6y2 + 12y + 8
The first one is your answer, hope this helped!
Answer:
<em>Answer B</em>
Step-by-step explanation:
<u>Fractions on the Number Line</u>
The number line contains an ordered sequence of the numbers, where the smaller numbers are at the left of the greater numbers.
This means -3 is to the left of -2, which is to the left of -1.
Number -2 1/4 lies between -2 and -3.
The only point lying on that interval is B.

Answer:
Option B
Step-by-step explanation:
To solve this, the Pythagorean Theorem is needed. For option A, to make the statement true, 4 squared plus 7 squared MUST equal 9 squared. So, if you take 16 and add 49 to it you do NOT get 81.
For option B, 5 squared plus 12 squared is the same as 25 plus 144. That equals 169, which IS 13 squared.
It is not option C because 20 squared plus 22 squared doesn't equal 24 squared
