Answer:
Step-by-step explanation:
<u>The area between the concentric circles:</u>
<u>If we tale π ≈ 3, we know R = 5 cm, we see r = R - 2 = 5 - 2 = 3 cm, then</u>
- A = 3(5² - 3²) = 3(16) = 48 cm²
Correct choice is B
Answer:
top left is "same" top right is "parallel"
we can tell a rectangle is also a square when both width and length are the same,
then,
solve for x
there is not solution, then the rectangle shown is not a square
Answer:
(n+4)(n+22)
Explanation:
Use FOIL
First - multiply n•n and get n2
Outside - multiply n•22 and get 22n
Inside - multiply 4•n and get 4n
Last - multiply 4•22 and get 88
You should have n2+22n+4n+88
Then add like terms so 22n+4n and get 26n
You would get n2+26n+88
The vertical line test is when you put vertical lines down the graph and if the point does not touch the line more than once, it passes and represents a function.
