Three polynomials are factored below, but some coefficients and constants are missing. All of the missing values of a, b, c, and d are integers.
1. x? - 8x + 15 = (ax + b)(cx + d)
2. 2x3 – 8x2 – 24x = 2x(ax + b)(cx + d)
3. 6x2 + 14x + 4 = (ax + b)(cx + d)
Fill in the table with the missing values of a, b, c, and d.

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

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.
