The negative in front of the second bracket means that it's times by -1 so each of their signs switches: 
3m^2+2n-m^2-2n 
Add like terms 
2m^2 
the 2n cancels out

Jeremy has $1200 in spending money for the fall semester of college. He needs to purchase car insurance at $120 for 4 months, $2
abruzzese [7]

Answer:

Jeremy Will have more than just $200 to spend on Christmas presents.

Explanation :

He has a total of $1200.

He spends a $120 for car insurance. (1)

He needs to spend $25 a week for lunch. He has to do this for 16 weeks so 25*16 = $400. (2)

He needs to spend $20 a week for entertainment. For 16 weeks that'll be 20*16 = $320 (3)

adding (1) (2) and (3)

We get Jeremy's total spending will be $840. Jeremy has $1200.

1200-840 = $360

So Jeremy will have $360 to spend on Christmas present.

A1 would be the first y value, which is 3 and d is the ratio ( distance between each y value) which is 3 ( add 3 to the y value to get the next one)

The answer is a1= 2, d = 3
