Chapter 3: Q3. (page 118)

Write an equivalent expression of $8 (z - 7)$ .

Short Answer

Expert verified

The equivalent expression is $8 z - 56$ .

Step by step solution

Step- 1- Apply the concept of distributive property

In this type of question, apply the concept of distributive property which means $a (b + c) = a b + b c$ .

Step- 2- Finding the equivalent expression

Since, the expression is $8 (z - 7)$ .

Now, apply the distributive law $a (b + c) = a b + b c$ in the above expression to get the solution,

$\begin{array}{l} = 8 (z - 7) \\ = 8 \times z - 8 \times 7 \\ = 8 z - 56 \end{array}$
