In this diagram, ABAC – AEDF. If the area of ABAC = 6 in2, what is the area of AEDF? D E F = 2 in A B C = 3 in, Area = [?] in2 Enter a decimal rounded to the tenths.​

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.

1 is c

2 is a

3 is a

step-by-step explanation:

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
