Lets set our x's apart first, the 5 can only be multiplied by 1 and 5 to get it so lets put a 5 in one side and a 1 in the other... it should look like (5x )(1x )
now we have a postive in the first term and a negative in the second, this means that there will be a positive and a negative sign... now lets see what can be multiplied by 50 that can add to be 15.. lets try 25 times 2 it gives you 50 but lets check if it gives you 15 in the middle,,lets set it up like this (5x+25)(1x-2) if you multiply these will you get 5x2+15x-50?? yes you will!! so which of these factors are alike to your answer?? well the only one would be (x-2), this means your answer would be letter C
Hope this helps
Answer:
perimeter: 12x-6
area: 6x-10
Step-by-step explanation:
PERIMETER:
6x-5(2)+2(2)
12x-10+4
12x-6
AREA:
6x-5•2
6x-10
·1/5n becomes 4/20n
·Leave 3/4 alone
·7/10n becomes 14/20n
·Combine like terms: 14/20n + 4/20n = 18/20n
·Simplify 18/20 to 9/10
·Final Answer : 9/10 - 3/4
Hope this helps you out in future problems!
Answer:
Your car is faster of course
Step-by-step explanation:
100 km would be 100000 meters. Then you would need to know that if Usain bolt ran 100 meters every 9.54 sec then in 100000 meters he would have ran 9540 seconds which is also known has 159 minutes, which is more than 1 hour so your car is faster.
Yes it is divisible by 2. The answer would be 2884.
