Question

Evaluate 7w - 14 when w =8 Show two ways to find the same value of the expression and make sure that one way uses distributive property

Answer 1

Answer:

42

Step-by-step explanation:

First Method

In this case we will substitute w=8 directly into the expression and solve:

$7w - 14$

When x=8, we get:

$7(8) - 14$

This gives us:

$56 - 14 = 42$

Second Method:

This time we factor

$7w - 14 = 7(w - 2)$

when w=8,

$7(8 - 2) = 7 \times 6 = 42$
