the inverse of x^5-3 ===>(x+3)^(1/5)

the inverse of x^4/7+27===>to solve it need to know if it's (x^4)/7 or x^(4/7)

the inverse of 1/x^2====> 1/(√x)

Leona [35]

Answer: 4 feet < Length < 21 feet

Step-by-step explanation:

From the question, the length of the rectangular fence is 4 feet more than its width and the perimeter of the fence is less than 42 feet. The range of the lengths of the fence will be:

Length is greater than 4 feet (4 feet more than the width. This means that the length must be at least 4 feet) and less than 21 feet i.e the length must be less than 1/2 of the perimeter which is 42/2 = 21. Therefore, the answer will be:

4 feet < Length < 21 feet
