Answer:8x+4w

Step-by-step explanation:

So the question is

3x+4w+7x-2x

We take the variables that are the same which are

3x

7x

-2x

We add all of these together

3x+7x+(-2x)=8x

8x is our answer, so we take 8x and add 4w to it

8x+4w

This is the final answer, because there is nothing else left to do

Answer:

C

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 1,950.00(1 + 0.08/2)(2)(4)

A = 1,950.00(1 + 0.04)(8)

A = $2,668.71
