Answer:
26
Step-by-step explanation:
If each row has an equal number of trees, you would divide the total number of trees by the number of rows. 858/33 is 26
The answer is 28
30 minutes is half of an hour so you have to divide 7 by 2 which is 3.5 and then multiply 3.5 by 8 to get 28
Since volume equals LxWxH it is 6x6x6= 216
Answer: C) (9x^4-x^3-x)/5
D) construction of the angle bisector.
So if you have a triangle that is not equilateral the perpendicular bisectors would not work so you need angle bisectors.
I have drawn a diagram
The green is the angle bisectors and the yellow the perpendicular bisectors.
You can see the problem straight away
