Answer:
10) 51°
11) 152
Step-by-step explanation:
10) 42 + 9 = 51
11) 45(3.5) + 22(-.25) = 157.5 - 5.5 = 152
I think it might be r= -3
Answer:
The answer is B.
Step-by-step explanation:
All the integers are positive.
Answer:
6
Step-by-step explanation:
The rational root theorem states that the roots must be factors of p/q
where p is the constant and q is the coefficient of the highest order term
p = 8 which has factors ±1, ±2,±4,±8
q = 1 which has factors ±1
The possible roots are ±1, ±2,±4,±8
--------------------
±1
which simplifies to
±1, ±2,±4,±8
6 is not a possible root
66 minutes is the correct answer
