When you combine like terms, you essentially add things that are similar, like integers or variables. Here, we have 2 integers and 1 variable. We will add the two integers and leave the 1 variable as it has no like terms to be added with.
So we have -12 -6p -(-2). When we have -(-n), that makes +n; when there is a minus sign in front of brackets, that flips the sign of everything inside the brackets — -(-2) becomes +2.
So now, we have -12-6p+2. We add -12 and +2 and get -10. So our expression looks like this: -10-6p, and thats it.
Dunnow what the formula is for
combinations vs permutations
combos, the order does matter and you can repeat
permutations, the order doesn't matter and once you use something, you can't repeate it
what you do is
(number of choices)^(number of slots y ou have to fill)
in this case
number of choices is 3 (3 fllavors)
number of slots=2 since 2 toppings
3^2=9
9 choices
chocolate-carmael
chocolate-strawberry
chocolate-chocolate
strawberry-carmael
strawberry-chocolate
strawberry-strawberry
carmael-chocolate
carmael-strawberry
carmael-carmael
9 choices
9/10 is the answer. 7/8 is 70/80 and 9/10 is 72/80
