what is the measure of an acute angle between two diagonals of the regular pentagon that originates from the same vertex?

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

answer: 5

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,
