Answer:
60 seconds
Step-by-step explanation:
step 1.) find how many meters it falls per second
40m / 4sec = 10m/s
step 2.) use the equation above to find in terms of the question
10m/s for 6sec = 10 x 6 ====> 60 seconds
To factor this quadratic equation into double brackets, you need to find two numbers that add together to equal 10, but also multiply to give you 9. These two numbers can be identified as 1 and 9, which will be the numbers you place in your parentheses as follows:
(x+1)(x+9)
