Question

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

Short answer

The equivalent expression is $8z-56$.

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$a(b+c)=ab+bc$ .

Step- 2-  Finding the equivalent expression

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

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

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