Answer:
To evaluate the expression 3x^2/y when x = 3 and y = 6, we substitute the given values into the expression.
Substituting x = 3 and y = 6 into the expression 3x^2/y, we get:
3(3)^2/6
First, we calculate the value of 3^2, which is 9:
3(9)/6
Next, we multiply 3 and 9, which gives us 27:
27/6
To simplify the fraction 27/6, we can divide both the numerator and the denominator by their greatest common divisor, which is 3:
27 ÷ 3 / 6 ÷ 3
This simplifies to:
9/2
Therefore, when x = 3 and y = 6, the expression 3x^2/y evaluates to 9/2.
