Complete the square for the given equation
x² - 2x + ____ + y² - 2y + _____ = 98
x² - 2x + (1) + y² - 2y + (1) = 98 + (1) + (1)
(x - 1)² + (x - 1)² = 100
(x - 1)² + (x - 1)² = 10²
Now the equation is in the form (x - h)² + (y - k)² = r²
Radius = 10
For the given right triangle, the perimeter is 60cm, so the correct option is D.

How to get the perimeter of the triangle?</h3>
We can see a right triangle, by using the Pythagorean theorem we can get the missing cathetus:
Now we know the measure of the 3 sides, then the perimeter of the given triangle is:
P = 15cm + 20cm + 25cm = 60cm
The perimeter of the triangle is 60cm.

1/3+2/5+4/3+3/5=8/3
Steps
A double negative makes a positive.
So, change all double negatives to positives (to simplify it)
1/3 + 2/5 + 1+1/3 + 3/5
What's the least common denominator here?
Yes, it is 15!
Change the fractions to that denominator
5/15 + 6/15 + 1+5/15 + 9/15
change 1+5/15 to 20/15, then add the fractions
Result: 40/15
Divide numerator and denominator both by the greatest common factor:5
8/3
