Express using algebra.

a. A movie theater has a rows, and b seats in each row. How many seats are in the theater?

b. A teacher handed out m notebooks which came in packs with c notebooks in each pack. How many packs were there?

c. A truck has a total of a pounds of fruit in boxes. How many boxes are on the truck if there are n pounds of fruit in each box?

d. What is the length of a rectangle whose perimeter is P, if the width is 6?

e. What number is 7 more than twice as much as x?

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

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!

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!

the answer is  

d.

8 m

hope you got it down chief.
