Answer:
-x - 3
Step-by-step explanation:
x-(2x + 3)
=> x-1(2x + 3)
=> x - 2x - 3
=> -x - 3
Therefore, this is the solution. Hoped this helped.

Anything to the 0 power is 1
and 1 to the any power is 1
so x can be any number
First thing you would do is distribute the negative on the outside of the parentheses to the inside terms:
9x - 5x + 7 = 39
Now, combine like terms:
4x + 7 = 39
Subtract 7 from both sides to get variables on one side of the equal sign and constants on the other:
4x = 39 - 7
4x = 32
Divide both sides by 4 to isolate the variable x.
x = 32 / 4
x = 8
Answer: The are 39,070,080 different ways the DJ can play the first 6 songs.
We will use the Fundamental Counting Principle to find the answer. Simply determine the number of choices for each position and multiply.
For the first choice there are 21 choices. Then, the number is reduced by 1 each time.
So to get the answer, we have to multiply the numbers below:
21 x 20 x 19 x 18 x 17 x 16
Answer:
B
Step-by-step explanation:
The standard form of a circle is

where h and k are the coordinates of the center of the circle and the radius is squared. The radius is easy...take the square root of 25 to get that the radius is 5. Since the pattern for the standard form is "x-" and "y-", if (x+2)^2 is the horizontal placement of the center, it actually was originally written as (x-(-2))^2, so the h coordinate is -2. Same goes for the vertical movement of the center. (y-(5))^2 means that the k coordinate is a positive 5.
