Answer:
c/-9+6=14
c/-9=14-6
c/-9=8
c=8×(-9)
c= -72
Therefore the answer is (b)
It is B because angle DBA is supplementary to angle DBE because together they create a straight line which equals 180 degrees.
Answer:
I think the constant is 2.
Step-by-step explanation:
5 is coefficient because it is with a variable. So 5 cannot be constant.
To determine the solution of the quadratic equation, use the quadratic formula which states that,
x = ((-b +/- sqrt (b² - 4ac)) / 2a
From the equation, a = 1, b = 14, and c = 112. Substituting these to the quadratic formula,
x = <span>((-14 +/- sqrt (14² - 4(1)(12)) / 2(1) = indeterminate
Thus, the equation does not a real number solution. </span>
