explaination plz :) :)
We need to find the number of perfect squares between 360 and 630
The first perfect square is the square of 19(361) and the last perfect square is the square of 25(625).
So total number = 7

Quantity B is greater should be correct answer

d can take all the numbers greater than -1, so range of d would be [1,infinity]. Also, for r, the range would be [-inf,2]. Hence, the intersection of 2 sets would be -1<=v<=2

since x=12 is a solution for y=x-3, it will give y=9 and base and height of triangle would be 9& 9

Hey,

Had a doubt - If x is a +ve number, and x>y, then must x^3 - x(y)^2 be positive ?

If you take the x common you’ll get x(x+y)(x-y).
In this x and x-y are always positive but (x+y) could be negative depending upon y

So entire term could be positive or negative
