A forest is predominantly made up of pine, maple, and oak trees. A sample of 72 trees shows 15 of the trees to be oak. If the forest has a density of 47 trees per acre—and it has 632 acres—approximately how many oak trees are in the forest? Round your answer to the nearest whole tree. a.6,100 oak trees
b.6,011 oak trees
c.6,188 oak trees
d.6,818 oak trees

hi how are you doing today, if you need just ask me.

step-by-step explanation:

could you provide figure.

i think the length is 12 and the width is 17

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
