Simplify 3^3
= (9-27) + (27-3)
= (-18) + (24)
= 6
216/24=9
9(144)=1296

Answer:
x = 12
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (6), x is a projection (x), and y is the other projection (3):
6 3
---- = -----
x 6
Cross multiply:
36 = 3x
12 = x
x = 12
Well the area of the triangle is 18 so Id figure if my math is correct x = 3
