Marco and drew stacked boxes on a shelf. marco lifted 9 boxes and drew lifted 14 boxes. the boxes that drew lifted each weighed 8 lb less than the boxes marco lifted. let m represent the weight of the boxes that marco lifted. which expression represents the total number of pounds drew lifted? 14(m−8)112m9(m+8)m−8

if m = weight of boxes and the boxes drew lifted were 8 pound less you would have (m-8)

 Marco lifted 14 boxes so the equation would be 14(m-8)

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.
