Which three of the following are in the same fact family as the equation below? 12.4 - 3.2 = 9.2

a. 9.2 - 3.2=12.4
b. 9.2 + 3.2=12.4
c. 12.4 - 9.2=3.2
d. 12.4 + 3.2=9.2
e. 3.2 + 9.2=12.4
f. 3.2 - 9.2=12.4

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.
