Answer:
Dividing logarithms is not the same as dividing the arguments of a logarithm.
Step-by-step explanation:
1) If we divide two logarithms then we'll find a value. This is not the same as dividing two arguments of the same base logarithms.
For example:

Then

2) Completing the table below to show it clearly:
Answer:
The height of the triangular prism is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The volume of the triangular prism is equal to

where
B is the area of the triangular base
h is the height of the prism
<em>Find the area of the base B</em>

we have


substitute and solve for x


4(x+7)=38
4x + 28 = 38 - distribute the 4 into x and 7
4x = 10 - subtract 28 from both sides
x = 2.5 - divide both sides by 4 to get x by itself
answer - x = 2.5
