The sum of 9/26 and -4/13

Mathematics
1 answer:
ohaa [14]3 years ago
8 0

Answer:

Step-by-step explanation:

Ok, well the first thing you need to do is make -4/13 have the same numerator as 9/26. Thankfully, 26 is a multiple of 13, so that step is easy:

-4/13 -> -8/26

Then you can add them together with ease.

9/26 + -8/26 = 1/26

Adding a negative number to anything is the same thing as subtracting.

Hello,
Answer D

1) if 4x+2>0 then |4x+2|=4x+2

(x³ + ³) / (x - y)<br> Do not include parentheses in your answer.
Lubov Fominskaja [6]

The simplified expression of \frac{x^3 + (-y)^3}{(x - y} is x^2+xy+y^2

<h3>Complete question</h3>

Simplify the expression: (x³ + (-y)³) / (x - y)

Do not include parentheses in your answer.

<h3>How to simplify the expression?</h3>

The expression is given as:

\frac{x^3 + (-y)^3}{(x - y}

Open the inner bracket

\frac{x^3 -y^3}{(x - y}

Apply the difference of two cubes to the numerator

\frac{(x-y)(x^2+xy+y^2)}{(x - y}


Cancel out the common factors

x^2+xy+y^2

Hence, the simplified expression of \frac{x^3 + (-y)^3}{(x - y} is x^2+xy+y^2
