Jeanne makes hair bows to sell at the craft fair. Each bow requires 1.5 yards of ribbon. At the fabric store, ribbon is sold by the foot. A. If Jeanne wants to make 84 bows, how many feet of ribbon must she buy?
B. If the ribbon costs 10¢ per foot, what is the total cost of the ribbon in dollars?

A:42 B:$4.20

Step-by-step explanation:

A: 84x1.5=126 126/3=42

B: 42x10=420=$4.20

let's fu(!

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
