What is the value of expression (x-y)^2 when x= 5 and y= -1

The value of the expression (x-y)² when x = 5 and y = -1 is 36

From the question, the given expression is (x-y)^2

First, we will write this expression properly,

The expression, written properly is (x-y)²

Now, to determine the value of the given expression [(x-y)²] when x = 5 and y = -1,

We will put the given values of the variables (x and y) into the expression and simplify.

The given expression is

(x-y)²

Now, put the given respective values of x and y into the equation,

That is, put x = 5 and y = -1

Then,

(x-y)² = (5--1)²

= (5+1)²

(NOTE: -- = +)

= 6²

= 36

Hence, the value of the expression (x-y)² when x = 5 and y = -1 is 36

All you have to do is plug the values into the equation.

(5 - (-1))^2 = 6^2 = 36.

y= -

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
