N= x+15 where n = nina, x = the amount hiked together and the 15 is how much she already walked.
First one is 1 x 10^6
second is 2 x 10^8
third one is 157 times
12.8 miles would take the 16 friends to split the trip into 16 parts
Assuming the numbers are exponents expect the coefficient of 2, top expression, -12x^3y^6, multiply bottom
and= 72x^4y^8
30, they was buuuuuuuurnt
nah but 30-1
c=0 maybe lol
