Question

Evaluate the expression for x = 4 and y = 5.

Answer 1

Answer:

$\large\boxed{B). \,41}$

Step-by-step explanation:

In this question, we would be plugging in the given numbers to the right variables and solving from there.

We know that:

• x = 4
• y = 5

Our equation is:

$6(x^2 -y) - y^2$

When you plug in the numbers, your equation should look like this:

$6(4^2 -5) - 5^2$

Now, you solve:

$6(4^2 -5) - 5^2\\\\\text{Lets start with the number inside the parenthesis}\\4^2\,\text{is the same as 4*4}\\\\6(16 -5) - 5^2\\\\6(11) - 5^2\\\\66-5^2\\\\5^2\,\text{is the same as 5*5}\\\\66-25\\\\\text{Finish by subtracting}\\\\41$

When you're done solving, you should get 41.

This means that B). 41 would be the correct answer.

I hope this helped you out.

Good luck on your academics.

Have a fantastic day!

Answer 2

Answer:

The correct option is B) 41.

Step-by-step explanation:

Consider the provided expression.

$6(x^2 - y) - y^2$

Substitute the value of x=4 and y=5 in the above expression and solve.

$6(4^2 - 5) - 5^2$

$6(16 - 5) - 25$

$6(11) - 25$

$66 - 25$

$41$

Hence, the correct option is B) 41.
