Area of square = a^2 = 4^2 = 4 x 4 = 16
answer
16
Answer:

Step-by-step explanation:
Whe have the function 
To solve this equation we must factor.
To factor, we need to find the points where the function is equal to zero. So we use the quadratic formula

Where:
a = 3
b = -6
c = 2
Then

finally the correct answer is 
There is 360* in a circle, so you would divide 360 by 20 to get 18.
Answer:

Step-by-step explanation:
Vertical Angles are congruent (equal)
78 = 5x - 2
80 = 5x
16 = x
