1. 1 hour is 3x20 minutes so distance is 3 km wi=hich is 3000 metres
2. same way as before but now 4x 1km is 4000 metres, minus the previous answer is 1000 metres.
3. 26 days x 24 hours (in one day) = 624 hours
4. A) 1 hour 45 minutes
B) 10:10, because add one hour and then minus 10 minutes (probably easiest way)
Answer:
I'm pretty sure it's y= 1/3x + 2
Step-by-step explanation:
Answer: I think the greatest common factor is 4x^2
Step-by-step explanation:
Find the numerical common factors. Which are 8, -12, and 20. Find the variable common factors for x^4, x^3, and x^2. Multiply them together. Then break down the factors on both sides and pick the biggest one. Finally multiply them together. (I’m sorry, I’m very bad at explaining things.)
Answer:
(2n+6)^2
Step-by-step explanation:
To solve this, you can use the given formula: x^2 + 2xy + y^2
In this case, 4n^2 is x^2, 24n is 2xy, and 36 is y^2. The next step is:
(2n)^2 + 2(2n)(6) + (6)^2
Since this equation fits into this formula ( x^2 + 2xy + y^2), we can do:
(2n+6)(2n+6) =
(2n+6)^2
Hence, the answer is (2n+6)^2
