Answer:
b is -mx+y and m is -b+y/x
Step-by-step explanation:
Answer:
(x-8) (x+2)
Step-by-step explanation:
x^2 – 6x – 16
Factor
What 2 numbers multiply to -16 and add to -6
-8 *2 = -18
-8+2 = -6
(x-8) (x+2)
If the shapes are similar, the correspondent sides are in proportion:

Let's plug the values and solve for x:

Multiply both sides by x to get

The only feasible solution, though, is
, because it wouldn't make sense to have negative lengths.
