Carla bought 66 inches of pink ribbon and 36 inches of white ribbon. She wanted to cut each ribbon into 6 equal pieces.

Which explanation correctly shows how to calculate the difference in length between one piece of pink ribbon and one piece of white ribbon?

A.
Step 1 Divide: 66 ÷ 6.

Step 2 Divide: 36 ÷ 6.

Step 3 Subtract the two quotients.

B.
Step 1 Divide: 66 ÷ 6.

Step 2 Divide: 36 ÷ 6.

Step 3 Add the two quotients.

C.
Step 1 Multiply: 66 × 6.

Step 2 Multiply: 36 × 6.

Step 3 Add the two products.

D.
Step 1 Multiply: 66 × 6.

Step 2 Multiply: 36 × 6.

Step 3 Subtract the two products.

I´m pretty sure it´s A but I think you should wait for other answers as well

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
