The mode is a term that is repeated the most.
And the one which is the repeated is 30.
Simplify the ration expression

start by seeing if anything in the numerator or denominator can be factored,
you should notice that you can factor out a 3 from 3x-6 in the numerator
when you do so, the result is

now, since there is an x-2 in the numerator and denominator, they "cancel" out since

however, only when

since

when you cancel out the x-2, you're left with 3
hence, your answer is C
-3/2 -15/10 this is called a negative number. Negative 1 and 5 tenths
I believe I already answered this question... did I get it wrong?
12,5,13 are Pythagorean triplets..
so, missing side will be 12 inches
hope it helps
