Answer:
I think is A. commutative property
I’m probably wrong but I got 52.5. I’m most likely wrong but hope I could help a bit
6÷2(1+2) = 6÷2*(1+2) = 6÷2*3 = 3*3 = 9.
y = -x² - 2x + 3
y - 3 = -x² - 2x + 3 - 3
y - 3 = -x² - 2x
y - 3 - 1 = -x² - 2x - 1
y - 4 = -(x²) - (2x) - (1)
y - 4 = -(x² + 2x + 1)
y - 4 = -(x² + x + x + 1)
y - 4 = -(x(x) + x(1) + 1(x) + 1(1))
y - 4 = -(x(x + 1) + 1(x + 1))
y - 4 = -(x + 1)(x + 1)
y - 4 = -(x + 1)²
y - 4 + 4 = -(x + 1)² + 4
y = -(x + 1)² + 4
