The width of a rectangle is 7 inches less than its length. The area of a rectangle is 20 square inches. Solve for the dimensions of the rectangle

3

Step-by-step explanation:

20/2 = 10

Which means 1 length and 1 side together will equal 10. If the width is 7 less than the length then you have to find 2 numbers that equal 10 but are 7 number away from each other.

length=8.5

width=1.5

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
