Answer:

Step-by-step explanation:
A suitable common denominator is 4k^2. (This eliminates the first and last choices.)

Hi there I know the answer but it was confusing so it has to be D or B
Well since it gives you 2 gas stations it wants you to compare prices
Als gas station will be A
At-one will be B
since station A has $3.259/ gallon I assume
and B has $3.199/ gallon
just subtract them
so 3.259 -3.199 = 0.06
gas is less at station B noticeably costs less so thats your first answer
for the next one if you bought gallon of gas at the cheaper station you'd be saving $0.06/gallon since we got the difference from subtracting them.
5x6 = 30 divided in half because its a triangle
=15
2x3 = 6
15-6 = 9

subtract the numbers:


subtract 9 from both sides

simplify

divide both sides by 6


decimal

Hope this helps :)
