Okay so this is going to be confusing but work from right to left. since you can’t do 0-5, borrow from the one next to the zero on the top, cross out the one and put zero and add a one on top of the zero which makes it 10. now you can do 10-5 to get 5. put the five down below the line. next solve the second column of numbers ( second to the right). since you cannot do 0- 3, like the last one, you have to borrow from the 7 over to the left. take one from there and cross the seven out and put a six. now you have 10-3 which is 7. put the 7 down. now do move to the next column and do 6-2 to get 4. put the four down below the line. move to the next column and do 2-2 to get 0. put the zero down below the line. lastly, we know the answer has to be negative so we are going to do 2-7 to get -5. put -5 down below the line and together to get the answer -502,275. i know that was very confusing but i hope it helped a little bit. i added a picture to clarify a little
<h2>Answer:</h2>
Shown below
<h2>Step-by-step explanation:</h2>First of all, we have the following points:
To plot these points, we need to graph a coordinate grid. Recall that a coordinate grid is composed of two perpendicular lines, that we call the axes and are labeled like number lines. The horizontal axis is called the x-axis while the vertical axis is called the y-axis, and these two axes intersect at a point called the origin. Next, let's plot each point as follows:
<h2>PART 1. Plot the points on your own coordinates grid and connect in alphabetical order. </h2><h2></h2>
Point a:
Let's stand at the origin and then move three units to the left and three units up. The resulting point is shown in the firs figure below.
Point b:
Let's stand at the origin and then move two units to the right and three units up. The resulting point is shown in the firs figure below.
Point c:
Let's stand at the origin and then move five units to the right and two units down. The resulting point is shown in the firs figure below.
Point d:
Let's stand at the origin and then move three units to down. The resulting point is shown in the firs figure below.
Point e:
Let's stand at the origin and then move three units to the left and two units down. The resulting point is shown in the firs figure below.
Next, let's connect connect the points in alphabetical order, so that the line are connected from a to b, from b to c, from c to d, from d to e and from e to a again. So the resulting graph is shown in the second figure. As you can see, this is an irregular pentagon.
<h2>PART 2. Decompose figure ABCDE into rectangles and triangles.</h2>Every pentagon can be divided up into three triangles. Hence, from the third figure. the triangles are:
ΔABE
ΔBDE
ΔBCD
Since a rectangle is a quadrilateral whose angles are all right angles, then there is no chance to obtain a rectangle from ABCDE. To obtain a rectangle, we'd need other points and this is not what the problem asks.
