Justify each step in solving the equation 4 + 1 = 7( − 3)+ 1 by writing a reason for each statement.
Statement Reason
4 + 1 = 7( −3) +1
4x=7(x-3)
4x=7x-21
-3x=-21
X=7

rounding to the nearest thousandth would be 452,000

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!

just pick what you think i need more time let me know if this
