Hannah and Caden just had business cards made. Hannah's printing company charged a one-time setup fee of $20 and then $7 per box of cards. Caden, meanwhile, ordered his online. They cost $17 per box. There was no setup fee, but he had to pay $10 to have his order shipped to his house. By coincidence, Hannah and Caden ended up spending the same amount on their business cards. How many boxes did each buy? How much did each spend?

i need more details sorry

step-by-step explanation:

c

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!
