Set t=0 so
x²-1936=0
(x-44)²=0
x=44 phones he must cell to break even
by definition of exponentiation;
by the distributive property of multiplication;
by the distributive property of exponentiation;
by grouping common terms and simplifying.
Slope of AB = 1/3 and slope of BC = -3 so these 2 lines are perpendicular
The same is true for all the other adjjacent pairs of lines.
Oppoitse lines are also paralllel ( slope of AB = 1/3 and slope of DC = 1/3) and other pair are both of slope -3.
So Its C
Answer:
c
Step-by-step explanation:
75 is supplementary to angle b. then angle a = 180-75=105
