B.) 20
If x goes from 2 to 4 it was multiplied by 2. you would do the same to the y. 10*2=20
Due to the order of operations the correct answer is 6+2*5=16
Let the smaller integer be x.
The larger integer is x + 1.
x(x + 1) = 420
x^2 + x = 420
x^2 + x - 420 = 0
The constant is -420.
Let's say you had 12 campers with you so
Your tent 1
Then you need to divide the campers into 3s so 4 groups of 3
1 tent for each group of 3
So take C divid it by 3 plus you're 1 tent
C = number of campers
Hope this helps
