Accepted Solution

A:
Answer:[tex]\large\boxed{B). \,41}[/tex]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 = 4y = 5Our equation is:[tex]6(x^2 -y) - y^2[/tex] When you plug in the numbers, your equation should look like this:[tex]6(4^2 -5) - 5^2[/tex]Now, you solve:[tex]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[/tex]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!
