Answer:

Yes

Step-by-step explanation:

Use the completing the square method:

16(x^2-x)+4

=16((x-1/2)^2 - (1/2)^2)+4

=16((x-1/2)^2 - 1/4)+4

=16((x-1/2)^2) - 16/4 + 4

=16(x-1/2)^2

=4^2(x-1/2)^2

The product of two square is itself a square.

there are 26 times in Washington high school as teachers.when all the teachers and students are seated in the 900 seat school au
krok68 [10]
So, I assume that you mean 26 students times the teachers. 
You can create two equations out of this information.
s = students while t = teachers
26t = s
900 - 9 = 891 seats being occupied
s + t = 891
You can use these two equations for substitution.
s = 891 - t
26t = 891 - t
27t = 891
t = 31
So, 31 teachers. Now plug that back into an original equation.
s + (31) = 891
s = 860
860 students.
