Answer:
d) 16x² -56x +49
Step-by-step explanation:
The square of a binomial difference will have the form ...
(ax -b)² = a²x² -2abx +b²
__
The sign of the linear term will be negative, which eliminates choices A and C.
The linear term will be double the product of the roots of the other two terms.
In choice B, the linear term has a factor of 5 that appears nowhere else, so that cannot be a perfect square.
Choice D factors as ...
16x² -56x +49 = (4x -7)² . . . . the square of a difference

Answer:
latest time he should get up in the morning 6:10 A.M
Step-by-step explanation:
given data
reach school at = 7:10 A.M
shower time = 20 minute
eat breakfast = 15 minutes
bus ride to school = 25 Minute
solution
we get here first total activity time after wake up to reach school is
total activity time = 20 + 15+ 25
total activity time = 60 minutes = 1 hour
so Hung must get up in the morning 1 hour before reach at school so he will be fit to arrive on time that is 7:10 - 1.00 = 6:10
(-N)/5=-5
(-N)=(-5)(5)
(-N)=-25
(-1)(N)=(-25)
N=25
