Which of the following ordered pairs make this equation true?
y = 3x - 2
A. (7,3)
B. (2,4)
C. (13,5)
D. (-1,5)

Evaluate cos2θ for cosθ = square root of 3/2

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?
