Answer:
ok so if we take length to be x we know width is x-3
the perimeter is the total length of sides, if you look at a rectangle you can see it has 4 sides with 2 length and 2 width. so perimeter is 2 times (x + x-3) = 26.
2x -3 = 13, 2x = 16, x = 8, 8 is length
the width is then 8-3 = 5.
Length = 8, width = 5.
X is equal to 15 and y is equal to 17
So the answer to this is A .x=15, y=17
Five plus four x is equal to 2x-9

Answer:
Step-by-step explanation:
Given the solution to an inequality
{x|x>2/3}
The solution set does not include 
, therefore, it must be open at the left. Recall that we use a curvy bracket ( to denote openness at the left.
Since x is greater than , the solution set contains all values of larger than up till infinity. Since infinity is an arbitrarily large value, we also use an open bracket at the right.
Therefore, another way to represent the solution {x|x>2/3} is:
The correct option is C.
