Trying to figure out how to simplify an expression and using this as an example. 3x+x+4x+2x

Hi there!!

Simplifying an expression is when you combine like terms. 

Like terms are when at least two values have a variable in common or no variable at all. For example, 5x and 9x are like terms because both have X. 9y and 2x are not. 2xy and 9y are still not. 

Moreover, if we were to simplify 3x+x+4x+2x, we can see that this expression is all like terms. SO we are going to simply add it all. 

3x+x+4x+2x
3x+4x+2x
7x+2x
9x

9x is your final answer.

Hope this is helpful!

The expression for 3x+x+4x+2x is
3x+x+4x+2x
3x+4x+2x
7x+2x
9x

9x is the final answer
Hope this helps a lot
Hope you get an A

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
