A hexagon will rotate onto its self at 120 degrees.
The answer to your question is 8, so letter C
I'll just assign a value of x and solve it so that I'll be able to arrange them in order from greatest to least.
I am assuming that x = 2.
4x + 9 ⇒ 4(2) + 9 = 8 + 9 = 179^x + 1 ⇒ 9² + 1= 81 + 1 = 82x² + 3 ⇒ 2² + 3 = 4 + 3 = 74x ⇒ 4(2) = 89^x ⇒ 9² = 81x² ⇒ 2² = 4
based on my assumption, the order from greatest value to least value is:1) 9^x + 12) 9^x3) 4x + 94) 4x5) x² + 36) x²
