Answer: 81

To get this answer, you do two things
1) Take half of the x coefficient 18 to get 9
2) Square the result from the previous step to get 9^2 = 9*9 = 81

This value is added on to get x^2+18x+81 which factors to (x+9)^2 confirming we have a perfect square trinomial

IgorLugansk [536]
I think the answer is 320miles, 3hs at 60mph = 180miles 2hs at 70mph = 140miles so 180+140=320miles

Please I have a 50% in this class ​
Sonbull [250]
I can’t solve them all for you, but I can teach you how repeating decimals work!

For example, 1. 0.3 with a line over the three means that the three repeats forever, so it’s equivalent to 0.333333333333….

Another example is 4, since it only repeats the number that has the line over it, it is equal to 0.025555555…

Hope this helps ☺️
