Answer:
2n+11
Step-by-step explanation:
really simple
Answer: its correct
Step-by-step explanation: and its correct cuase its the answer you choose
The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.
(n^2 -4) = (n -2)(n +2)
Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...
(n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2
This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).
_____
If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).
Answer:
x = -5
Step-by-step explanation:
Step 1: Write out equation
15x - 24 - 4x = -79
Step 2: Combine like terms
11x - 24 = -79
Step 3: Add 24 to both sides
11x = -55
Step 4: Divide both sides by 11
x = -5
Step 5: Check step
Plug in -5 into the original equation
15(-5) - 24 - 4(-5) = -79
-75 - 24 + 20 = -79
-99 + 20 = -79
-79 = -79
Daniel -- 12 balls
Manuel -- 12 balls × 2 = 24
Kendra -- 24 balls x 2 = 48
12 + 24 + 48 = 84 balls total
