9x^2+5y
(Simplify your answer. Type an integer or a tion.)

Answer 1

By substituting x=4 and y=3 into the expression 9x^2+5y, we calculate the terms separately and find that the numerical value is 159.

Step-by-step explanation:

The question asks us to find the numerical value of the expression 9x^2+5y given that x=4 and y=3. To solve this, we substitute the given values into the expression:

First calculate the term with the exponent:

9x^2 = 9(4)^2 = 9(16) = 144

Now calculate the multiplication:

5y = 5(3) = 15

Add both terms to find the numerical value:

144 + 15 = 159

Therefore, the numerical value of 9x^2+5y is 159 when x=4 and y=3.
