Answer:
As in 4 hours , 20 men can cut 30 trees. So, in 1 hour , 20 men can cut 30 trees / 4. So, in 6 hours, 20 men can cut 30 * 6 trees / 4 = 45 trees.
Step-by-step explanation:
done
Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
F(3)=2*3-8=-2.
Hope that helps.
The slope would be 3/4 because 5 - 2 is 3 and -1 - (-5) is 4. Hope this helps!
