. The perimeter of a triangle can be represented by the expression P = 4x2 – 5x+1. The length of one side is x² – 2x – 4 and the length of
the other side is 2x2 – 8x – 6. Write a polynomial that represents the third
side.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
