Its an easy one first thing you look at is the -(5), if u looked closely their is a - sign in front of the 5 its a -1 do if you multiply the -1 to 5 so it will be -5 and then multiply -5 ,3 time it will be positive 125 because u multiply the -5 , 3 times. I hope that helped a lott. :)
Your Answer is 286/15 OR 19 1/15. Why?
Take the 2 from the first fraction and multiply is by the denominator (5) to get 10, and then add it to the numerator (2) to get 11. Now you have 11/5
Then, take the 8 and multiply it by 3 to get 24, then add it to the numerator to get 26/3
26 x 11 is 286 and 3 x 5 is 15. So you get 286/15. 286 goes into 15 nineteen times (do 286 divided by 15 and you'll get 19.0666667, so you simply do 19 x 15 and you'll get 285, with 1 left, giving you 19 1/15)
Like terms are "from the same family"
In the given expression, 18p and 2p are like terms.
Let's add them:
18p+2p-79+89
20p+10
I really hope it helps you!
Note: a² - b² = (a-b)(a+b)
9x² - 16y² = (3x)² - (4y)² = (3x - 4y)(3x + 4y)
