16*X² +81
The answer is 3
(4x+9i)(4x−9i) = (4x+9i)*4x -9i((4x+9i)) = 16x2 +36i -36i -81i2 = 16x² -81(-1)
= 16x² +81
You would multiply 50x16 being 16 ounces= 1 pound and than divide that by 10
Answer:
x=-2
Step-by-step explanation:
-6/18=x/6
simplify the -6/18 into -1/3,
-1/3=x/6
cross product,
3*x=-1*6
3x=-6
x=-6/3
x=-2
Volume because of weight and surface
