Answer: 11 because it all works out.
Answer:
7/24
Step-by-step explanation:
Let
x-----> the shaded area

Because the complete circle represent the 100\%
and
9514 1404 393
Answer:
(x -y -1)(x +y)
Step-by-step explanation:
The expression can be factored by grouping.
x^2 -y^2 -x -y = (x^2 -y^2) -(x +y)
= (x -y)(x +y) -1(x +y)
= (x -y -1)(x +y)
