Answer:
A&D
Step-by-step explanation:
8% of something is the same thing as 8% times that. If we use that, we get the answers A and D
3. 5mn ( 2m + 6n + 1 )
4. 4a^3b^2c ( 18a^2b - 8c )
5. (X-15)(X+15)
6. -4(y-4.5)(y+4.5)
8. 2X(X-10)(X+10)
i am not sure if no. 8 is right
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
Distance formula: distance = sqrt((x2-x1)^2 + (y2 -y1)^2))
Distance = sqrt(( -3 - -3)^2 + (9-4)^2))
Distance = sqrt(25)
Distance = 5
Answer: 5
