Answer:
Again assuming we're cleared for immediate take off, it takes around 20 minutes to climb to cruise altitude, at an average ground speed of (say) 200 knots. This means we've covered about 70 miles, which the cruising aircraft would have covered in just over 10 minutes. So this final phase has cost us another 10 minutes

X is 4 y is zero. So he can do four math assignments if this doesn't include breaks.
Answer:
16
Step-by-step explanation:
Given
x² + 8x = 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = 4 + 16, thus
(x + 4)² = 20 ← equivalent equation
