Friend again :/ A parking garage near Kirk's house is 4 stories tall. There are 49 open parking spots on the first level. There are 4 more open parking spots on the second level than on the first level, and there are 9 more open parking spots on the third level than on the second level. There are 49 open parking spots on the fourth level. How many open parking spots are there in all?

what do you need me to answer?

step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

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!
