Answer:
-3x³ - 4x² + x - 9
Step-by-step explanation:
-5x³ + 2x² + x - 7
- <u>(-2x³ + 6x² + 0 + 2)</u> remember: when you subtract, you 'add the opposite'
-3x³ + (-4x²) + x + (-9)
Answer:
34.2 or 34.20
Step-by-step explanation:
Sometimes they accept 34.2 without the zero, but that's up to you
Think of this as a proportion: 2.4 is to 100, as 34 is to L ("L" for "Long piece.")
Cross multiply to get 2.4 L = 3400, then divide both sides by 2.4 to be left with
L = 3400/2.4, so
L = 1416.666...
So the longer piece of wood is 1,416.66... inches long.
Hope this helps!!:)
treat the tree trunk as a cylinder
v= pi x r^2 x h
using 3.14 for pi
3.14 x 3^2 x 10 = 282.6 cubic feet
282.6 * 45 = 12, 717 pounds
It is an irrational number
