Answer:
14, 22
Step-by-step explanation:
x+y = 36
2×x - y = 6
=> x = 36 - y
=> 2×(36 - y) - y = 6
72 - 2y - y = 6
-3y = -66
3y = 66
y = 22
=> x = 36 - 22 = 14

The denominator can't be equal to 0.

The domain is all numbers except -3 and 3.
Answer:
2d-388 or 2(d-194)
Step-by-step explanation:
25(d-10)-23(d+6)
25d-250-23d-138
25d-23d-250-138
2d-250-138
2d-388
factor out or simplify,
you get 2(d-194)
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
