EXPLANATION
The outermost square tile has side length,

The area of a square is given by;

We substitite the given expression for the side length into the formula to obtain,


We expand using the distributive property to obtain;

This gives us:


The last choice is correct.
Answer:
y=25.5
Step-by-step explanation:
To find y, you need to get it by itself. Ask yourself, what is being done to y, then to undo that, do the opposite. For example, if 3 was added to y, you would need to subtract 3 to cancel out the 3. In this case, what is being done to y? It's being divided by 3. So, you multiply by 3 to cancel that out. Whatever you do to one side of an equation, you also have to do to the other. So,
8.5=
Multiply both sides by 3
3(8.5) = 3(
) multiply on the left side, and on the right side the 3s cancel out
25.5=y
