The first (and most typical) way to find distance of two points is by using the distance formula.

One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|
13*18
x*y =234
x+y=31
we know the 2 # have to be double digits and both between 10-20
find 2 values that * to a number that ends in 4. Those are the ones value
1*4 11 and 14
2*2 12 and 12
3*8 13 and 18
only 13 and 18 add up to 31 and multiply to 234

i think the question is incomplete another angle having 10 be x then the relation was found to be
x + alpha= 100
Y = 3^x
To the x power.
y = 3^(1) = 3
y = 3^(2) = 9
y= 3^(3) = 27 and so on...
