If consecutive angles of a 4-sided figure were complementary, then all four of them <span>would add up to 180°. But that's a problem, because we all know that the sum of all </span>four angles in any 4-sided figure is always 360°. So the answer must be: 'No<span>'.</span>
First of all, the shaded part is under the line, so it is a smaller than, so we can eliminate D
next, look at the vertex, it is at (5,5), which means when x=5, whatever is inside the absolute symbol has a value of zero, and y will be 5
so the answer is A
The area of the shaded region will be the area of the rectangle minus the area of the white square inside of it:
((x+10)(2x+5)) - ((x+1)(x+1))
First, FOIL both of the areas separately:
(2x^2 + 5x + 20x + 50) - (x^2 + x + x + 1)
Simplify within the parentheses by adding like terms:
(2x^2 + 25x + 50) - (x^2 + 2x + 1)
Now, subtract one equation from the other:
2x^2 + 25x + 50
-x^2 - 2x - 1
= x^2 + 23x + 49
This will be the equation for the area.
The value of x that will make the proportion true is

Answer:
b
Step-by-step explanation:
polygons is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit
