PLS HELP I ONLY HAVE 15 POINTS

4/6

Step-by-step explanation:

6r + 3b = 9

?g/3b

2/3 = 2g/3b

6 + 3 + 2 = 11

15 - 11 = 4

4 yellow marbles : 6 red marbles

4/6

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.
