Given the two expressions below: 4x2 − 8 square root of x + 9 3y2 + 2x + 6 is the sum of the two expressions above a polynomial? why or why not? a. yes, because whenever two expressions are added, their sum will be a polynomial. b. yes, because both expressions are polynomials, so their sum will be a polynomial. c. no, because at least one of the expressions has two variables, so their sum will not be a polynomial. d. no, because one of the expressions is not a polynomial, so their sum will not be a polynomial.

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
