Answer:
The spruce tree had a faster groth rate.
Step-by-step explanation:
It maintained a constant rate and went from 6,5 to 8,6.
spruce tree his .5 and pine tree is .25
The variable in that expression is x
(2x - y)(4x2 + 2xy + y2) =
8x3 + 4x2y + 2xy2 - 4xy2 - 2xy2 - y3 (combine and simplify like terms)
= 8x3 - y3
170 km/h
