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
It need to be more clear for me to read
The median of the data is 60. That means the two middle numbers divided by 2 = 60.
(x + x + 2) / 2 = 60...multiply by 2
2x + 2 = 120
2x = 120 - 2
2x = 118
x = 118/2
x = 59
x + 2 = 59 + 2 = 61
so ur numbers go : 26,29,42,53,59,61. 70, 75, 82, 93
The degree is 3.

I’m pretty sure that the first one is one
