Geometric mean of
3 and 12: √3 * 12
3 * 12 = 36
√36 = 6
the value of the geometric mean of 3 & 12 is 6
The volume of the pyramid is changed by a factor of 125
<u>Solution:</u>
Given that, each side of a pyramid is multiplied by a factor of 5.
We have to find how will the volume of the pyramid changes?
Now, we know that, volume of a pyramid 
Now, each dimension is multiplied by factor of 5.
Then, volume of new pyramid 

Volume of new pyramid = 125
volume of old pyramid.
Hence, the volume of the pyramid is changed by a factor of 125.
Answer:360
Step-by-step explanation:
Answer:
7.7u - 5.1v + 14.5w
Step-by-step explanation:
Given length:
Side A = (1.2u+1.8v) centimeters,
Side B = (6.5u+8.7w) centimeters
Side C = (5.8w-6.9v) centimeters
Perimeter of a triangle = side A + side B + side C
= (1.2u+1.8v) + (6.5u+8.7w) + (5.8w-6.9v)
= 1.2u + 1.8v + 6.5u + 8.7w + 5.8w - 6.9v
Collect like terms
= 1.2u + 6.5u + 1.8v - 6.9v + 8.7w + 5.8w
= 7.7u - 5.1v + 14.5w
Therefore, the perimeter of the triangle is 7.7u - 5.1v + 14.5w
