Answer:
1. 30 minutes
2. 15 minutes
3. 30 minutes
4. 60 minutes/ 1 hour
5. 45 minutes
Step-by-step explanation:
1. 60 - 45 = 15
15+15 = 30
2. 30 - 15 = 15
3. 45 - 15 = 30
4. 60 - 30 = 30
30 + 30 = 60
5. 60 - 15 = 45

Answer: the answer is x+8= 1
The sum of function is a way of adding two or more functions together
The values of x for which f(g(x)) = 0 are -2/3 and -1/3
<h3>Sum of functions</h3>
The sum of function is a way of adding two or more functions together
Given the following functions
f(x) = x² - 2x
g(x) = 6x + 4
f(g(x) = f(6x +4))
f(6x+4) = (6x+4)² - 2(6x+4)
(6x+4)² - 2(6x+4) = 0
(6x+4) = 0 and 6x+4-2 = 0
x = -2/3 and -1/3
Hence the values of x for which f(g(x)) = 0 are -2/3 and -1/3
