In algebra, the inequality will refer to a number, or range of numbers, which are either greater than, greater than or equal to, less than, or less than or equal to a fixed value. This can be shown on a number line using lines and circles. The line indicates the range of possible values. The circle is the end point of the line.
Consider this option: 1. area_rombus=a*h, where a=6 - the length of the side, h - height. h=area_rombus/a. 2. area_sq=a², where a=6 - the length of the square. area_sq=36, area_rombus=4/5 *36=28.8. 3. according to the item 1 h=area_rombus/a=28.8/6=4.8.
