The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle
s of the pentagon are equal, which expression represents the measure of two angles? 2x2(20 – 32x + 25x2)
2(8x2 – 13x +10)
5x2(8x2 – 13x + 10)
5(3x2 – 8x + 5)
Hemoglobin is found in the red blood cells and are responsible for binding onto oxygen molecules. By binding to the oxygen, it can transport it to through out the body where it is needed.
