The gradient of x axis is zero. As such, the gradient of the line parallel to x-axis can only be zero
Answer:
Step-by-step explanation:
First of all let's notice that 
while our original polynomial is real. So we can rule out the even options B and D. At this point, if the polynomial has a factor of 
it means tha 
is a zero of the polynomial. Let's check both 2 (for option a) and -2 (for option c)
At this point 2 is a zero, and our final factoring is a
Any quadrilateral which can be inscribed in a circle, is called a cyclic quadrilateral.
The main theorem about these quadrilaterals is the following:
In any cyclic quadrilateral, the sum of the measures of the opposite angles is 180°.
This means, m(∠S)+m(∠Q) =180°,
thus
(7x-2)+(5x+14)=180
12x+12=180
12x=168
x=168/12=14
Thus the measures of angles Q and S are respectively:
7x-2 = 7*14-2=96 (degrees) and
5x+14=5*14+14=6*14=84 (degrees)
