Answer:
278
Step-by-step explanation:
y = 9(85)-487
y = 765-487
y = 278
Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
At first find the area of rectangle:
(x + 4)*(x + 1) = x^2 + 5x + 4
Then find the area of triangle:

Then you must do like this
Area of rectangle - Area of triangle = Area of the shaded
x^2+5x+4 - (
