Answer:
Step-by-step explanation:
2b^2 - 3b + 4a^2........a =-6 and b = 8
now we sub
2(8^2) - 3(8) + 4(-6^2)
2(64) - 24 + 4(36)
128 - 24 + 144
272 - 24
248 <==
Answer:
45 mph
Step-by-step explanation:
Given: Distance travelled= 330 miles
Time taken= 6 h
Lets find out speed of car drove.
Formula; 
Speed= 
∴ Car´s speed is 55 mph.
As we have been informed that car´s rate of travel slows by 10 mph
∴ we have to reduce the current speed of car by 10 mph; 
The new slower rate of travel is 45 mph.

Step-by-step explanation:
3x=9
divide each side by 3
9/3=3

Integrating an equation from boundary x₀ to x₁ gives you the area underneath that boundary.
So to find the boundary that split the equation into 2 equal areas, the boundary must lie somewhere between the 2 place to want to split up. In other word, <em>a</em> is the end boundaries of the first integral and the starting boundary of the second integral.
Since the two area must equal to each other, set the two integral equal to each other and solve for a.
