Question

Evaluate the given expression if x = 25, y = 10, w = 11, and z = 18.

(see the image)

Answer 1

The answer will be 2,205
(25-10)^2+10*11*16=2,205

Answer 2

D

Explanation:

So we have the expression:

`(x-y)^2+10wz`

And we want to evaluate it when x=25, y=10, w=11, and z=18.

So, substitute these values for the variables:

`=(25-10)^2+10(11)(18)`

First, subtract within the parentheses:

`=(15)^2+10(11)(18)`

Square 15:

`=225+10(11)(18)`

Now, multiply the terms on the right. 10 times 11 is 110:

`=225+110(18)`

Multiply:

`=225+1980`

Finally, add:

`=2205`

So, our answer is D.

And we're done!
