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

(see the image)

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!

answer: idk

step-by-step explanation:

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
