Short Answer

Expert verified

$(2 + 9) 2 = 22$ .

Step by step solution

Step-1 – What are real numbers?

Real numbers are simply the combination of Whole numbers, Integers, Rational and Irrational numbers in the number system.

Step-2 – Distributive Property of Multiplication

Suppose a, b, and c is three real numbers.

Distributive Property of Multiplication

Property: $(b + c) a = b \cdot a + c \cdot a$

Example: $(3 + 4) 12 = 3 \cdot 12 + 3 \cdot 12 = 36 + 48 = 84$

Step-3: Use the distributive property to evaluate the expression.

Distributive Property of Multiplication

Property: $(b + c) a = b \cdot a + c \cdot a$

$(2 + 9) 2 = 2 \cdot 2 + 9 \cdot 2 = 4 + 18 = 22$

$(2 + 9) 2 = 22$
