Answer:

<em>4 + 7x – 2</em>

Step-by-step explanation:

<u>Equivalent Expressions</u>

Let's find out which expressions are equivalent by simplifying them. One of the expressions should be not equivalent to the other three.

Simplifying

2x + 2+ 2x + 3x -8=7x-6

Now for the second expression

4 + 7x -2=7x+2

The third expression simplifies to

-2 + 5x + 2x - 4=7x-6

Finally, this is the simplification for the expression

8x - x - 6=7x-6

As seen, the only expression not equivalent to the other three is 4 + 7x – 2

Verdich [7]
The answer is 81 < < 105

Explanation: Since the car gets 27 mpg in the city and gets 35 mpg on the highway, you can set it up in the inequality 27 < < 35 and this represents the range a car can drive for 1 gallon, so to find the range for 3 gallons, you multiply this inequality by 3.

27(3)<<35(3)
27(3)=81
35(3)=105

Then you can insert the numbers into the inequality to get 81<<105.
