The 40 feet of fencing which covers at least 182 square feet gives the possible lengths of x as x ≥ 13 or x ≤ 7
<h3>How can the area be expressed as an inequality?</h3>
Length of the fencing = 40 feet
Number of sides covered = Three sides
Area of the fencing ≥ 182 square feet
Length of the shorter side of the pen = x
The area is therefore;
2•x² - 40•x + 182 ≥ 0
2•(x² - 20•x + 91) ≥ 0
2•(x² - 13•x - 7•x + 91) ≥ 0
2•(x•(x - 13) - 7•(x - 13) ≥ 0
Which gives;
The solution to the inequality and the possible lengths of <em>x </em>are;<em> </em>x ≥ 13 or x ≤ 7

Answer:
i think it's 73 units in the cube
Total amount = $80
Amount left= $54.74
So amount spent = 80 - 54.74 = $25.26
Let the number of pounds be ‘x’
8.42 x = 25.26
x = 3
