i think this is what you mean
First we have to figure out how many hours have passed. Since 1PM also means 1300 hours, we'll subtract 9 from 13. 13-9=4. therefore, 4 hours have passed. if it gains 4 minutes every hour, we'll multiply the amount of hours that have passed by the amount the clock gains every hour. 4x4=16. now we subtract 16 from 1300 because the clock is ahead of the real time, but remember and hour only has 60 minutes! 1300-16=1244. Therefore, the correct time is 12:44PM.

B) (x + 7)^2 = 20
<h3>
Step-by-step explanation:</h3>
You can subtract 34 from the original equation to get
... x^2 +14x = -29
Now, you can add the square of half the x-coefficient, and you will have ...
... x^2 +14x +49 = -29 +49
... (x +7)^2 = 20 . . . . . . matches selection B

Step-by-step explanation:
t - 4t² + 2t³ = t(1 - 4t + 2t²)
= t(2t² - 4t +1)
≠≠≠≠ t(2t - 1)(t -1)
