Which answer choice is correct ?

P=Q

Step-by-step explanation:

The angles of a triangle should add up to 180 Degrees.To figure out what is true about the values we need to solve for both angles.

To solve for P we need to do 80+20=100 and now we subtract the degrees we already have from what we need 180-100=80 P=80

Now we do the same for Q. 45+55=100 180-100=80  Q=80

We know that P=Q This is also symmetric property which you'll probably learn later on.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
