Step-by-step explanation:

In mathematics,  the "Bar models" are used to represent known an unknown quantities and they are very useful to solve problems that involve Addition, Subtraction, Multiplication and Division.

For this exercise you need to analize the data given and observe the bar model provided in the picture attached.

In this case, you can identify two parts in the bar model. These are:

and

Then, knowing those parts, you need to find the whole.

You can notice in the bar model that, if you combine (or add) the bars that represent and the bar that represents , you will obtain the whole bar.

So, you can identify that the bar model represents an Addition.

Therefore, based on the explained before, you can conclude that the algebraic expression shown in the given bar model is the following:

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
