What is the Commutative Property of Addition?
According to the Commutative Property of Addition, how numbers that are are added are ordered do not change or affect the sum of the numbers. For example, a + b = b + a.
1. To simplify -(x - 4) using the distributive property:
= -1(x) -1(-4)
= -x + 4
Therefore, the simplified form of -x + 4 is: B. - x + 4
2. m - 4 can be written as a phrase as: B. 4 less than m
3. The property that illustrates the expression, 3 + x = x + 3, is: D. cumulative property of addition.
4. Irrational numbers cannot be expressed, as a simple fraction. √3 cannot be expressed in simple fractions. Therefore, √3 is classified as: B. irrational.
