Using properties of the logarithm, you can rearrange the integrand as
Then recall that the integral of 
is
(or you can find that out by integrating by parts) and so
-7 is less than -6 and -6 is greater than -7.
The absolute value of -7 is greater than the absolute value of -6 and the absolute value of -6 is less than the absolute value of -7.
To grandparents house :
140/56 = 2.5 hours
Return trip :
140/50 = 2.8 hours
Total time : 2.8+2.5 = 5.3 hours
Absolutely, over result will match in part b and c
<h3>What is Geogebra Tools?</h3>
Geogebra tools are software which is used to study an absolute geometry with zero errors.
Since, Geogebra contains various tools, In part b we have drawn a square through polygon command. Its allows to select the number of sides, so we select 4 cause square requires 4 equal sides.
Now, we very it in c part just by drawing a 4 connected lines which have 90° adjacent angles.
Here, by comparing their geometry it seems identical
Thus, the result, in part b and c matches for each other.

No, because the sum of two sides must be larger than the third.
