Delonna walks 4 miles per day for exercise. the total number of miles m she walks equals 4 times the number of days d she walks. what is the dependable variable? what is the independent variable? write the equation that represents the relationship between the m and d.

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.
