320/8=40
247.5 is the answer I hope this will help u bye and god blesses u!
Remember
difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
and the undistributiv propeoryt
ab-ac=a(b-c)
so we have

undistribute and factor

cancel out the one ( (u-2)/(u-2)=1)

is result
3x² + xy2 – 3xy-y? >> 3x² - xy - y
line 1: = (3x² + xy2)+(-3xy – y?)
ANS 3x² - xy - y 《Correct》
line 2: = x(3x + y2) - y(3x – y2)
ANS 3x² - xy +2y²
line 3: = (x-y) (3x +y?)
ANS 3x² - 2xy - y²
If it incorrect, I'm sorry.
B). is not always true.
If it IS true, then the rhombus is a square.
