The way I would look at it is that Sophia types 15 words per minute faster than Patty so every minute Sophia is 15 minutes closer to what Patty has done. 510/15=34 so after 34 minutes Sophia will have caught up to Patty
-3/4x+8=13
-3/4x=5
answer is false
In a standard binomial equation: ax² + bx + c = 0
To complete the square; divide the middle coefficient "b" in half and square it to find "c".
(-5/2)² = 25/4
x² - 5x + 25/4 = 25/4
completes the square:
(x - 5/2)² = 25/4
