Assume a mature sequoia tree requires at least 0.6 m^2 of exterior canopy area per cubic meter of trunk volume. Also assume that the canopy can be modeled by a cone whose slant height is 4 times its radius, and that the trunk of the tree can be modeled by a cone whose height is 12 times its diameter. What is the minimum base radius of canopy required for a sequoia with trunk diameter 5 m? Round your answer to the nearest tenth. PLEASE ACTUALLY ANSWER THE QUESTION, I'VE SENT THIS QUESTION TWO TIMES ALREADY AND GOT NONSENSE JUST FOR THE POINTS

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
