I need all the answers please :(

Question

Find the like terms in the expression
1.) y + 1.2y + 1.2z
2.) simplify 2 + 17x - 5x + 9
3.) simplify 3(5 = 6) - 4
4.) Factor 81 – 27p

Answer 1

actually, you need to learn how to solve these questions.

"Like terms" have the same variables. To simplify expressions, collect the like terms into a single term. For example,

y + 1.2y + 1.2z
= (1 + 1.2)y + 1.2z
= 2.2y + 1.2z

For factoring, look for the biggest thing that can be a factor of each term. For example,

64-16p = 16(4-p)

Now see what you can do with the other problems (including fixing the typo in #3).

Okay thank you guys
