liberstina [14]

Step-by-step explanation:

"12 more than the quiotent of a number n of and two decreased by 4"

$\left(\dfrac{n}{2}-4\right)+12$

$\left(\dfrac{n}{2}-4\right)+12=\dfrac{n}{2}-4+12=\dfrac{n}{2}+8$

Put n = 4 to the expresssion:

I have a small question what is this-

Cerrena [4.2K]

Answer:

Step-by-step explanation:

negative 5 is less then -3 is the statement. so saying that -3 is less than five, is false.

remember your number line.

-5_-4_-3_-2_-1_0_1_2_3_4_5_6

five sure is to the left of three, and saying that three is to the right of five is the exact same thing.

What is the numerator of the simplified sum?

katen-ka-za [31]

Answer:

Step-by-step explanation:

First, factor $x^{2}$ +3+2

Which equals (x+1)(x+2)

Then rewrite the expression with the common denominator

The fraction should now look like this

x+3(x+2)/(x+1)(x+2)

Now expand... you should have

x+3x+6/(x+1)(x+2)

Combine like terms and you get

4x+6/(x+1)(x+2)
