The answer is A
For a function, all you really need to do is plug in any “in” number to the equation to find the “out” number
For example: plugging in 5 into equation 1 would be:
f(5) = 9(5) + 4 = 49
If you keep doing this to each of the other “in” values, you would get the “out” values
First:
Break the shape into parts, this shape can be broken into 3 parts.
Next :
Put the equation for each shape
Shape 1 ( left shape)
L x h
5.4 in x 4.8 in = 25.95 in
Shape 2 (middle shape)
L x H
5in x 4.8in = 24in
Shape 3 ( right shape)
L x H
7.9 in x 4.8 in = 37.92 in
Last:
Add them all up
25.95 in
+ 24in
37.92in
——————
87.87in

87.87 in 2
I hope this helped and that I was right, have a nice day.
So we know that it's already 5 seconds behind on the first day.
On the second day, it's 6 seconds behind.
And on the third, it's 7 seconds behind.
And so on...
The difference between the day, and the seconds is 4.
This means, that whatever day it is (say 17 for example), and add 4, will come to how many seconds behind (17 + 4 = 21 in this case)!
So we subtract 29 by 4, to find the day:
29 - 4 = 25 days.
