Answer:
38cm
Step-by-step explanation:
1. The perimeter of a square can be found with the formula
2. Since its length and width are whole numbers, it must be either
1 x 18,
2 x 9 or
3 x 6
3. Using the formula in step 1, we can found that the perimeter in these cases are
38
22
18
respectively
4. Compare those perimeter we found in previous step, it's obvious that the greatest is 38. Solved.

Answer:
162
Step-by-step explanation:
Since the given line
has slope
The equation of the line perpendicular to it must have a slope which is the negative reciprocal of ,
The slope of the perpendicular line
Using the slope intercept form,
We substitute
This implies that,
Since
lies on this line , it must satisfy its equation.
That is
This implies that
The line therefore has equation,
Answer:
(3x^2-5x-5)/(x^2+x) <--- answer
Step-by-step explanation:
3x/(x+1) - 5/x = (3x^2 - 5(x+1) )/[ x(x+1) ]
= (3x^2 - 5x - 5)/(x^2 + x)
