At first find the area of rectangle:
(x + 4)*(x + 1) = x^2 + 5x + 4
Then find the area of triangle:
\frac{(x+1)(x-3)}{2} =  \frac{x^2-2x-3}{2}
Then you must do like this
Area of rectangle - Area of triangle = Area of the shaded
x^2+5x+4 - (\frac{x^2-2x-3}{2})

The sum of 2 numbers is 44 the smaller number is 16 less than the larger number what are the numbers
Anon25 [30]
X=27 and y=11
if you let each number equal x and y we know the sum is 38 so x+y=38
and the smaller is 16 less than the larger
. so if we say the smaller number is 7 then x-16=y
these can be solved as a simultaneous equation. x+(x-16)=38
2x-16=38
2x=54
x=27
(27)-16=y
y=11
so the answer is x=27 y=11
