I need help with this math problem.

$2

Step-by-step explanation:

Intial fee is x. Number of stops is y. You can set up these equations.

You can subtract one from the other:

         x+8y=14

       - x+4y=8

       –––––––

              4y=6

We now know that 4y=6. The first equation had 4y, so we can put 6 instead of 4y.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

6e14 is the answer.
