Answer:
33 units²
Step-by-step explanation:
vertical and horizontal lines through E will break the rectangle into 8 congruent triangles. The upper two shaded triangles can slide neatly down their hypotenuse faces to fill the lower un-shaded areas. The shaded region is shown to be exactly half of the rectangle
A = ½(11)(6) = 33 units²
No (3,6) is the solution for the first equation only
20x^2-24x-3

Answer:
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
Step-by-step explanation:
Cos 2x+sin x
use Trigonometric identities.
cos (2x) = cos (x + x) = cos x cos x - sin x sin x
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
