Use the quadratic formula to solve the equation. if necessary round to the nearest hundredth x^2-6=x a. x=2,3 b. x=-2,3 c. x=2,-3 d. x=-2,-3

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.
