Answer:

Step-by-step explanation:
3x(x − 2)(5x + 2)
- (x − 2)(5x + 2) expand
- 5x² - 8x - 4
- 3x ( 5x² - 8x - 4) expand
- 15x³ - 24x² - 12x
By rearranging it:
-3x-2x-22xy+4y
=-5x-22xy+4y answer
we need to know the height the length and the width
Answer:
Yes
Step-by-step explanation:
We need the half-life of C-14 which is 5,730 years.
Now, we will need a half-life equation:
elapsed time = half-life * log (bgng amt / ending amt) / log 2
We'll say beginning amount = 100 and ending amount = 41
elapsed time = 5,730 * log (100/41) / log 2
elapsed time = 5,730 * log (

) / 0.30102999566
elapsed time = 5,730 * 0.38721614327 / 0.30102999566
elapsed time =
