Which of the following functions best describes this graph? A. y = (x + 1)(x - 2) B. y = (x-2)(x-2) C. y = x^2 - 5x + 6 D. y = x^2 - x +5

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.

3; 9 is 8 to -4
