When you subtract flip the signs of the second set.
2x^2+5-4x+3
Now combine like terms
2x^2-4x+8
Final answer: B
Checkpoint A-> time being 1:00pm total miles driven being 120 and
checkpoint B-> time being 3:00pm and the total miles being 208
The distance between two checkpoint A and B is 208 - 120 = 88 miles
Now the time between the two checkpoints = 3.00 - 1.00 = 2 hours
We need to find car speed between the checkpoints
We know Distance = speed * time


Speed = 44 miles per hour
7 ( 5x - 6)
35x - 42 is the answer
Answer:
486
Step-by-step explanation:
Formula: Area = base · height ÷ 2
So, 36(b) · 27(h) ÷ 2 = 486
