Operations with Rational and Irrational Numbers MA.9-12.N-RN.B.3 - [Standard] - Explain why the sum or product of two rational numbers is rational; that the SUM of a RATIONAL number and an IRRATIONAL numberis IRRATIONAL and that the PRODUCT of a nonzero rational number and an IRRATIONAL number is IRRATIONAL Which expression could represent a Rational number? -a Both -a and -b -b Let 'a' represent a non-zero rational numberand let 'b' represent an irrational number Which expression could represent a Rational number? Let 'a' represent a non-zero rational numberand let 'b' represent an irrational number a + b a + a b + b Let 'a' represent a non-zero rational numberand let 'b' represent an irrational number Which expression could NOT represent a Rational number? a2 ab b2 The other zero must be rational The other zero must be irrational The other zero can be either rational or irrational The other zero must be non-real Consider a quadratic equation with integercoefficients and two distinct zeros. If one zero is Irrational, which statement is true about the other zero? Which expression could represent a Rational number? ab b2 -b a + b Let 'a' represent a non-zero rational numberand let 'b' represent an irrational number Select the appropriate option for...
