Which is enough information to prove that u parallel to v? Lines u and v are cut by transversal t. Clockwise from top left, the angles formed by t and u are 1, 2, 3, 4; formed by v and t are 5, 6, 7, 8. Angle 2 is congruent to angle 4 Angle 4 is congruent to angle 8 Angle 6 + angle 7 = 180 degrees Angle 3 + angle 4 = 180 degrees

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

there are infinitely many solutions.

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!
