Answer:
2 x² - 6x -5
Step-by-step explanation:
<u><em>Expansion:-</em></u>
Given that the expression
(8x²-7x-2)-(6x²-x+3)
= 8x² - 6x² - 7x +x -2 -3
= 2 x² - 6x -5
Answer:
I'm sorry but there is no diagram
What is the question so I can slove
Answer:
first 2.70, 4.00 , 7.20 , 7.65 , 6.00 , 12.60 , 62.50 , 45.00 ,32,00 , 12.60 and 2.00 done
Step-by-step explanation:
all correct
Trains depart after every 4 minutes.
Total time train takes to complete a circuit= 24 minutes
Evan sets off at 8:30 am, so he will be back at 8:54 am.
So time of trains coming in opposite direction:
8: 34 am
8:38 am
8:42 am
8:46 am
and 8:50 am
5 trains coming in opposite directions.
Now the trains started at 8:06 am from the stations are:
8:06 am
8:10 am
8:14 am
8:18 am
8:22 am
and 8:26 am.
So there are 6 trains started the circuit at 8:06 am.
Now total number of trains=6+5=11 trains
Answer: 11 trains will pass on complete circuit.
