Answer:
D
Step-by-step explanation:
So we have the expression:
And we want to evaluate it when x=25, y=10, w=11, and z=18.
So, substitute these values for the variables:
First, subtract within the parentheses:
Square 15:
Now, multiply the terms on the right. 10 times 11 is 110:
Multiply:
Finally, add:
So, our answer is D.
And we're done!
