Solve the equation
9x² – 29x – 28 = 0
Give your answers to 2 decimal places when appropriate

x = 4 or x = 0.78

Step-by-step explanation:

9x² – 29x – 28 = 0

2 roots: x = ((-(-29) ± √(-29)² - 4 x 9 x (-28)) / (2 x 9)

               = (29 ± √841 + 1008) / 18

               = (29 ± 43) /18

x = 72 /18 = 4     or

x = -14 /18 = - 0.78

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
