The Candy Store held a raffle, and Matt won the grand prize. He won a gift card to the store, as well as a bag of giant lollipops. He gave 21 lollipops to his friends, and he kept the remaining 7 lollipops. Which equation can be solved for n to find the total number of lollipops in the bag? A) n 21 = 7 B) n − 21 = 7 C) n + 21 = 7 D) 21n = 7

B:N-21=7

Step-by-step explanation:

If you subtract the total by the ammount of candy he gave you will get the amount of lollipops he have left

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
