Answer:
there are 8 million different phone numbers whose phone numbers whose digits aren't 0 or 1
Answer:
f = 26
d=112
e=42
Step-by-step explanation:
as far as what i can see, the first given angle is 112 and the second angle is 42.
These two angles are the angles on one straightline, therefore the missing angle will be 180 - 112 - 42 = 26 (Supplementary angle). This angle is not required and it is the missing angle on the left hand side. However, this angle should be equal to that of f (Opposite angle).
By the same way, d and e are the two opposite angles for 112 and 42, respectively.
Answer:
x = 28
Step-by-step explanation:
(3x + 6^o) = 90^o
3x = 84^o
x = 28
Answer:
positive
Step-by-step explanation:
The discriminant is positive
If there are 2 real roots ( where it crosses the x axis), then the discriminant is positive
