Well because there's and equal amount on each of the 8 pages, you'd do 128/8 which will show that there's 16 stamps per page.
The answer is C: 44 degrees
<span>Simplifying
(2x + -7y ) = 0
Multiply
(2x + -7y) * (x + y) </span><span>
(2x * (x + y) + -7y * (</span><span>x + y)) = 0
</span>((x * 2x + y * 2x) + -7y * (x + y)) = 0<span>
</span>Reorder the terms:
((2xy + 2x2) + -7y * (x + y)) = 0
((2xy + 2x2) + -7y * (x + y)) = 0
(2xy + 2x2 + (x * -7y + y * -7y)) = 0
(2xy + 2x2 + (-7xy + -7y2)) = 0<span>
Reorder the terms:
(2xy + -7xy + 2x2 + -7y2) = 0
</span>
<span>Combine like terms: 2xy + -7xy = -5xy
(-5xy + 2x2 + -7y2) = 0
</span>Solving -5xy + 2x2 + -7y2 = 0<span>
Solving for variable 'x'.
Factor a trinomial.
(2x + -7y)(x + y) = 0
