Can you solve this quadratic by taking the square root?: x^2-6x=-8

Step-by-step explanation:

To solve this you could complete the square, use the quadratic formula, or factor it. This equation is easily factorable.

x^2-6x+8=0

(x-2)(x-4)=0

So x=(2,4)

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.
