Answer:
B
Step-by-step explanation:
Because the formula for the area of a rectangle is length times width, all you have to do is multiply 15 by 15 and it should get you 225 as your answer
Answer:
The radius of circle is 4
Step-by-step explanation:
Given as :
The equation of circle is given as :
x² + y² = 16
Now The standard equation of
( x - h )² + ( y - k )² = r²
where h , k are center of circle
r is the radius of circle
From given circle equation x² + y² = 16 can be written as
( x - 0 )² + ( y - 0 )² = (4)²
So, The center of this circle is ( h , k ) = ( 0 , 0 ) And radius of circle = 4
Hence The radius of circle is 4 Answer
(x + 1) - (-2x - 5)
First, simplify. / Your problem should look like: x + 1 + 2x + 5
Second, gather like terms. / Your problem should look like: (x + 2x) + 1 + 5
Third, simplify. / Your problem should look like: 3x + 1 + 5
Fourth, simplify. / Your problem should look like: 3x + 6
Answer: 3x + 6 (D)
Answer:
70
Step-by-step explanation:
You know the fourth number in this pattern is 15, and that they are all consecutive. With this information you know that the fifth number will be 16, and by counting backwards from 15 you can figure out all of the numbers are 12, 13, 14, 15, and 16. Now, to find the sum of these numbers you must add them together.
This is what it could look like: 12+13+14+15+16
Now to find the answer you need to calculate what the addition would equal, which is 70.
