d/dx √x/√(x + 1)
= d/dx √[x/(x + 1)]
= d/dx [x/(x + 1)]^(1/2)
= (1/2)[x/(x + 1)]^(- 1/2)
= (1/2)[x/(x + 1)]^(- 1/2) * (x + 1)^(-2)
Explanation:
√a/√b = √(a/b)
√x = x^(1/2)
Chain rule:
d/dx f(g(... w(x))) = f’(g(... w(x))) * g’(... w(x)) * ... * w’(x)
Quotient rule:
d/dx f(x)/g(x) = [f’(x)g(x) - g’(x)f(x)]/[g(x)]^2
Given the perimeter and length of the garden, the width of the garden was extended by 4 feet
<h3>How to find width of the garden</h3>
- Length of the garden = 12 feet
- Width of the garden = 7 feet
- Width extension =( 7 + w) feet
Perimeter = 2(length+ width)
46 = 2{12 + (7 + w)}
46 = 2(12 + 7 + w)
46 = 2(19 + w)
46 = 38 + 2w
46 - 38 = 2w
8 = 2w
w = 8/2
w = 4 feet

Answer:
Total time taken by Laurie to cover all kitchen walls = 15 hours
Step-by-step explanation:
Given:
Time taken by Laurie to cover 20% of kitchen walls = 3 hours
Find:
Total time taken by Laurie to cover all kitchen walls
Computation:
Total time taken by Laurie to cover all kitchen walls = Time taken for 20%[100%/20%]
Total time taken by Laurie to cover all kitchen walls = 3[10/2]
Total time taken by Laurie to cover all kitchen walls = 3[5]
Total time taken by Laurie to cover all kitchen walls = 15 hours
Im not sure but maybe a square.
