Answer:
a. x is the width of the fence in feet and y is the length of the fence in feet , f = 2x+ 2y equation represents that the fence is twice the width and twice the length , x>10 represents that the width should be atleast 10 feet , y >8 represents that the length should be at least 8 feet , 3f<120 represents the cost constraint. it says that the fencing cost $3 per foot and should cost less than or equal to 120 . b. yes, i agree. this is because the inequality f>0 implies that the length of the fencing should be greater than 0. I hope this helps ! :)
10 * 100 = 1000 so... 10^3 would equal 1000 too

Step-by-step explanation:
The possible values of x are 3 and 7
<h3>Solving rational expressions</h3>
Given the rational expression below;
√60-8x = x - 9
Square both sides to have:
(60-8x)² = (x-9)²
60-8x = x²-18x+81
Equate to zero to have;
x²-18x+81 - 60 + 8x = 0
x² - 10x + 21 = 0
x² -3x-7x +21 = 0
x(x-3)-7(x-3) = 0
x = 3 and 7
Hence the possible values of x are 3 and 7
