Which of the following will result in a rational answer?

1.multiplying pi by a fraction
2.adding the square root of a non perfect square to a whole number
3.adding the square root of a perfect square to pi
4.multiplying a fraction by a repeating decimal.

a ratio is comparing 2 numbers. so i think the answer is 1 , because first you have to multiply y/x then divide to find ur ratio! so that would make it a rational answer and/or fraction.

Step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
