Adilation maps points b, c, and d onto b'. c', and d' respectively. choose all of
the true statements.
a. cd ic'd
b. the scale factor is
bc bd
cbc = b'd'
d. abcd ab'c'd

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 !

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!

answer is 17
