Hey there! :) 

5n(3n - n + 8)

Simplify.

(5n × 3n) + (5n × -n) + (5n × 8)

Simplify.

(15n²) + (-5n²) + (40n)

Remove parenthesis

**Remember : a negative times a positive is always a negative, a positive times a positive is a positive, and a negative times a negative is a positive**

15n² - 5n² + 40n

Combine like terms.

(15n² - 5n²) + 40n

Simplify.

10n² + 40n → final answer :) 

~Hope I helped!~

8 <br> 7<br> /<br> 8<br> + <br> 9 <br> 13<br> /<br> 16<br> what is this in a mixed number.
FinnZ [79.3K]

Answer:

18 and 11/16

Step-by-step explanation:

I converted the two numbers into improper fractions which leaves me with

71/8+157/16

I thenn made sure I had common denominators, which means I need to multiply the first number by 2/2 and I'm left with:

142/16+157/16

I can now add the 2 numbers together and I get:

299/16

now we just need to convert the number into a mixed number by dividing, and I am left with:

18 and 11/16
