Given
x² + 34x
To complete the square
add ( half the coefficient of the x- term )² to x² + 34x
= x² + 2(17)x + 17²
= x² + 34x + 289 ( with c = 289 )
= (x + 17)² ← perfect square
Answer:
x= 1.75 y= 6.75

Answer:
76 minutes
Step-by-step explanation:
The computation is shown below:
Since mark would take 1 hour and 15 minutes i.e. 60 + 15 = 75 minutes
And, emily takes for a minute = 1 minute
So, the number of minutes taken by Mars to drive is
= 75 + 1
= 76 minutes
