The given quadratic equation is
Group the constant terms on the right hand side.
Divide through by 5.
Add the square of half the coefficient of x., which is 
to both sides of the equation.
The left hand side is now a perfect square.
Take the square root of both sides;
or

To find the answer,we need to first find out their hours spent individually.
Rishi spent:
=2×3/4
=6/4hours

Hope it helps!
Noah is right because 75% of 10 is 7.5 and 10% of 30 also equals 7.5
Euclid used a somewhat different parallel postulate in trying to avoid the notion of the infinite. He observed that when two parallel lines are intersected by a third line, called a transversal, then if you measure two angles formed by these three lines, on the same side of the transversal and between the parallels, they will add to (that is, they will be supplementary). Such angles are called same-side interior angles<span>:</span>
