8 - 15 means subtract the positive number 15 from 8.
8 - 15 = 8 + (-15) = -7
8 - (-15) means subtract the negative number -15 from 8.
Subtracting a negative number is the same as adding a positive number.
8 - (-15) = 8 + 15 = 23
8 - 15 = -7, and 8 - (-15) = 23. The expressions mean different operations and have different answers.

I explain down below:
Step-by-step explanation:
First, you divide the combined rectangle into separate parts. Then you find the area of the first rectangle. Then the second and/or third one.
After all the areas have been solved, you add all of the areas together.
Hope this helps!
The answer is B.
A linear function is a first-order polynomial, which is of the form y = ax + b. It is called first-order because the power of x is 1.
A second-order polynomial is of the form y = ax^2 + b; which eliminates A. This is also known as a quadratic function.
C. can be simplified to y = 2/3 - 7/x, which probably has a name as well.
D. can be simplified to y - y = 3x/8 + 1/8, which is 0 = 3x + 1 or x = -1/3. Not a linear function
