Consider the following sets.

Answer:
[2,3] is the answer
assuming you didn't have equal symbols under the inequality signs, you know and
.
Step-by-step explanation:
Ok let's solve 3x+4>13 or 1/2 x+3<4.
Let's begin with 3x+4>13.
3x+4>13
Subtract 4 on both sides:
3x>9
Divide both sides by 3:
x>3
Now the other 1/2 x +3<4.
Subtract 3 on both sides:
1/2 x<1
Multiply both sides by 2:
x<2
So we have x>3 or x<2
If we graph this, this will give us better idea of what is and isn't a solution.
~~~~~~~~O x<2
O~~~~~~ x>3
------------(2)---------(3)---------
The only numbers not included are between 2 and 3 (inclusive).
So if x is between [2,3] then A or B has no solution.

<h2>Answer:</h2>
<u>, "six and one over two ft".</u>
Let's considerate the fact that the garden has a <u>square shape</u>.
<h3>1. Finding values of interest.</h3>Amount of fence that the gardener already has: ft.
Length of one side: ft.
If one side measures ft, and the square garden has 4 sides of equal length, because it's a square, then we must multiply the measure of one side by 4 to find the total length of fence needed:
The gardener already has , which equals
. Hence, the difference between the amount needed and the amount that the gardeneralready has will give us the remaining amount required. Let's do that:
