Find the area of the rectangle with a length of (5x + 4) and a width of (3x - 2).

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

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
