4 because 8 x 3= 23 but 8 x 4= 32 so thre will be some left over.
The correct answer is d) 4x² - 4x + 1.
The area of a square is found by squaring the side length:
(2x-1)² = (2x-1)(2x-1) = 2x*2x - 2x*1 - 2x*1 - 1(-1) = 4x² - 2x - 2x + 1 = 4x²-4x+1
Answer:
I could be wrong, but I believe that the answer is D, none. This is because there is only proof of one congruent side and angle.
