who will answer this 2 questions correct I will mark him/her as a brainliest. if the length of Suez Canal on a map of drawing scale 1 : 1400000 is 70 km, then it's length on the map=cm. the second question is the sum of edges of a cube is 24 cm then it's volumecm3 don't write anything wrong cause ik the answers... Good Luck​

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!

10+4√2 is the answer. i dont have the time to explain.
