To test for a triangle, the two smallest sides added together have to be greater than the third side.
3.95 + 4.56 > 8.65
8.51 > 8.65
this is false
4.56 + 8.65 > 10.31
13.21 > 10.31
could be it
4.56 + 8.65 > 13.21
13.21 > 13.21
no, this would mean they're equal
4.56 + 8.65 > 20.25
13.21 > 20.25
this is also false

Step-by-step explanation:
Answer:
<u><em>13.896 kg</em></u>
Step-by-step explanation:
Volume of Gold Bar = Area of [Trapezium x Length of Bar]
Length of Bar = 16 cm
Area of Trapezium = 2 × Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 × 5 × 3 = 7.5 cm²
2 × Area of Triangle = 2 × 7.5 = 15 cm²
Area of Rectangle = 6 × 5 = 30 cm²
Area of Trapezium = 15 + 30 = 45 cm²
Volume of Gold Bar = 45 × 16 = 720 cm³
Density of Gold = 19.3 g/cm³
Mass of Gold Bar = 720 × 19.3 = 13896 g = 13.896 kg
Mass of Gold Bar = 13.896 kg
Therefore the <u>mass</u> of the Gold Bar is: <em><u>13.896 kg</u></em> (kilograms).
Answer:
ln 3
Step-by-step explanation:
3 ln 3 - ln 9
We can rewrite 9 as 3^2
3 ln 3 - ln 3^2
We know lnx^a = aln x
3 ln 3 - 2 ln 3
ln 3
