Question

In the following expression, n is a rational number: Which expression below is equivalent to this expression?
A. -n(-0.7 + (-0.7))
B. 0.7n + 0.7n
C. -0.7n - 0.7n
D. -0.7xn + (-7.0)x(-n)

Answer 1

Answer:

None

Step-by-step explanation:

The given expression is $-0.7(n+(-n))$

When we apply the distributive property, we will obtain:

$-0.7(n+(-n))=-0.7n+-0.7(-n)$

An when we check the options none of them is equivalent to the given expression.

You might be tempted to choose option D but the -0.7 changed to -7.0
