What is the value of v?

An exterior angle is equal to the sum of the two opposite inside angles.

v + 42 = v + v + 2

Simplify:

V + 42 = 2v + 2

Subtract 2 from both sides:

V + 40 = 2v

Subtract 1 v from both sides:

40 = v

v = 40

constants mean the stopped points or the points on a graph that nothing is changing, hope this

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!
