Chapter 2: Q7. (page 73)

Use the distributive property to evaluate the expression.
$2 (x - 6)$

Short Answer

Expert verified

$2 (x - 6) = 2 x - 12$ .

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: $a (b - c) = a \cdot b - a \cdot c$

Example: $8 (12 - 4) = 8 \cdot 12 - 8 \cdot 4 = 96 - 32 = 64$

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

Distributive Property of Multiplication

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

\begin{array}{l} 2 (x - 6) = 2 \cdot x - 2 \cdot 6 = 2 x - 12 \\ 2 (x - 6) = 2 x - 12 \end{array}
