B is the answer hope this helps :)
circumference = 2 x PI x radius
42 = 2 x 3.14 x radius
42 = 6.28 x radius
radius = 42 / 6.28 = 6.687
= 6.69 inches
Answer:
3x³ - 12x + 4
Step-by-step explanation:
The opposite of a polynomial P is -P.
You find the opposite of P by multiplying it by -1.
P = -3x³ + 12x - 4
-P = (-1)( -3x³ + 12x - 4) Distribute -1 to each term
= (-1)(-3x³) + (-1)(12x) - (-1)(4) Multiply each coefficient by -1
= 3x³ + (-12)x - (-4)
= 3x³ - 12x + 4
