By searching up what is the square root of the number you have
Answer is -pi
Let x be this unknown number. Adding on x to pi gets us the expression x+pi
If we set x+pi equal to zero (which is a rational number) and solve for x, we get
x+pi = 0
x+pi - pi = 0 - pi
x = -pi
so adding pi to -pi will lead to 0 since
x+pi = -pi+pi = 0
3/5 is 60% 3/15 is 20% divide 60% by 20% and you have a 3 hope this helps
(x - 4)(x + 3) = x^2 + 3x - 4x - 12 = x^2 - x - 12
