Answer:
Part c
Step-by-step explanation:
In quadratic equations of real coefficients, the complex roots always occur in conjugate bases. It means, if, 2 + 3i is one of the roots and then the second root must be 2 - 3i.
4 hours for 18
7 hours for 25.50
Difference in hours: 7-4 = 3
Difference in cost: 25.50 - 18 = 7.50
7.50 / 3 = 2.50
A. They charge 2.50 per hour.
B. 2.50 x 4 = 10
18 - 10 = 8
The flat fee is 8 dollars
C. 8 + (2 x 2.50) = 13 dollars
Answer:
2x(x2-2x-15)
2x(x-5).(x+3)=0
x=0
x=5
x=-3
Step-by-step explanation:
Answer:
48 is your answer.
Step-by-step explanation:
What you want to do is follow PEMDAS.
Parenthesis are first. You will subtract 32 and 8 to get 24.
6 x [(24)/4+2] You will then divide 24 and 4 to get 6.
6 x[6+2] you will then add 6+2 to get 8.
6 x 8 = 48 is your answer.
