Kingsley must multiply the measure in centimeters by 1 / 2.54 to get a unit conversion equation in inches.
<h3>How to derive a unit conversion formula?</h3>
Kingsley knows the conversion rate between inches and centimeters and wants to derive a formula. Both the inch and the centimeter are length units and we can represent it by the following ratio:
y / x = 2.54 (1)
Where:
- y - Length, in centimeters.
- x - Length, in inches
Then, we clear the variable x in (1) to find the unit conversion formula:
x = y / 2.54 (2)

2370 / (2/5) = x / 1...2370 to 2/5 = x to 1
cross multiply
(2/5)(x) = (2370)(1)
2/5x = 2370
x = 2370 * 5/2
x = 11850/2 = 5925 <== their entire goal
To get f(h(x)), we simply plug h(x) into the x value(s) of f(x), resulting in
2(x²+1)-1=2x²+2-1=2x²+1
For g(f(x)), we plug f(x) into the x value(s) of g(x), resulting in
3(2x-1)=6x-3
