How do i find the length of
——
ab

As you know, in a parallelogram the opposite side are equal

So,

AB = DC

6x - 8 = 3x + 4

6x - 3x = 8 + 4

3x = 12

x = 12 / 3

x = 4

Therefore,

6x-8

= 6(4) - 8

= 24 - 8

= 16 units

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
