First step is to factorize the given expression as follows:
2x^2 + 7x - 15 = (2x-3)(x+5)
This means that the two roots of the equation are 3/2 (or 1.5) and -5
Now, we will get r and s:
we are given that the value of r is greater than the value of s, since 1.5 is greater than -5, therefore:
r = 1.5
s = -5
If a, b and c are the lengths of a right triangle and c is the longest side, then:

We have a = 18cm, b = 24cm and c = 30cm. Substitute and check:

<h3>Answer: It's the right triangle.</h3>
The answer in an improper fraction is
47/36
As a mixed number, it is 1 11/36
Hope you become an expert at this soon :)
