Since both of the angles are supplementary, you'd set the expressions up into an equation equal to 180(degrees). 
So, your equation should look like: 
                       22x + 4 + 35x + 5 = 180. 
Next, you combine your like terms so that your next move will look like: 
                       57x + 9 = 180. 
Then you'd follow the subtraction and division property, so your next moves will look as the following: 
                       57x + 9 - 9 = 180 - 9 equals 171
                       57x / 57 = 171 / 57 equals 3
So, finally, your answer is: x = 3.

Answer to B6 is I
Step-by-step explanation:
 The given function is f(x) = 9·x² + 54·x - 66
The extremum of the function are found as follows;
d(f(x))/dx = 0 = d(9·x² + 54·x - 66)/dx = 18·x + 54
∴ 18·x + 54 = 0 at the maximum or minimum points
x = -54/18 = -3
Given that d²(f(x))/dx² = 18 > 0. x = -3 is a minimum point
Given that the function is a quadratic function, we have;
1) Points to the left of x = -3 are decreasing
2) Points to the right of x = -3 are increasing.
