The answer is 36 because in order to find area you multiply length and width so:
A= L x W
9 x 4 = 36
To simplify that expression you'll join like terms.
8x + 4 - 5
8x - 1
If you are given the measure of angle 4, then we know angle 2 is equal since it is a vertical angle. The angle of a line is 180 degrees, so subtract the measure of angle 4 (and/or 2) which will give you the angle measure for both angle 1 and 3, since those are also equal due to vertical angles. Hope that helped! :)
The correct answers are 1. D, 2. A, 3. A, 4. A, 5. A
