Hi Larry
x^3 - 168 = [ 24(x-2)] / 2
x^3 - 168 = (24x - 48)/2
x^3 - 168 = 12x - 24
Subtract 12x - 24 to both sides
x^3 - 168 - (12x - 24) = 12xx - 24 - (12x - 24)
x^3 - 12x - 144 = 0
Now, factor the left sides
(x - 6)(x^2 + 6x + 24) = 0
Set factors equal to 0
x - 6 = 0 or x^2 + 6x + 24 = 0
x = 0 + 6 or x^2 + 6x + 24 - 0
x = 6
Answer : X = 6
Good luck !
No problem, that's why Brainly exists! :)
Karen is right, as every equilateral triangle has equal angles. The angles in every triangle must add up to 180°, and if all the angles are equal in an equilateral triangle, that must mean each angle is 60°. (180 ÷ 3 (because three sides in a triangle) = 60). Anything under 90° is acute, that means Karen is right because 60 < 90, and is therefore acute.
