Answer:
Step-by-step explanation:
A six sided figure has a total of 720 degrees for its interior angles. That comes from the formula (n - 2) * 180 where n is 6.
4 * 180 = 730.
So add up what you know plus x and make it equal to 720.
112 + 133 + 128 + 100 + 120 + x = 720 Combine the left.
593 + x = 720 Subtract 593 from both sides.
x = 720 - 593
x = 127
D. 3(x - 1)(x+3)(x + 2).
3(x - 1)(x + 3)(x + 2)
= 3(x - 1)(x^2 + 5x + 6)
= 3(x^3 + 5x^2 + 6x - x^2 - 5x - 6)
= 3(x^3 + 4x^2 + x - 6)
= 3x^3 + 12x^2 + 3x - 18.
D, A, I cannot read the rest of #3, C, C.
