How would you explain the value in context to someone who had never heard of this measurement?
what would you expect for the total monetary value of your prizes from 4 attempts at this game? (to answer this
question, check the introduction to this lesson; do not do anything complicated like developing a tree diagram for all
of the outcomes from 4 attempts at the game.)

-7/8y²+3

Step-by-step explanation:

It seems like we are just combining like terms here. Like terms have the same variable raised to the same power. We have three terms here: two of them are y² terms and one is just a 3, so we can combine those two like terms and then just add 3.

5/8y²-3/2y²= -7/8y²

Now we just plop the three on the end and we're done!

-7/8y²+3

Have a wonderful day!
