Answer 2

The expression is equivalent to n + n - 0.18n is 1.82n

Given :

The expression n + n - 0.18n

To find :

The expression is equivalent to n + n - 0.18n is

A. 1.82n

B. 1.18n

C. n - 0.18

D. 2n - 0.82

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is

n + n - 0.18n

Step 2 of 2 :

Simplify the given expression

$\sf n + n - 0.18n$
