Rule for 1 is the rule for 1 is 14 times 3.5^x and it is exponential
The second one is is also exponential and the rule is 32 times .25^x and the last one is is linear and the rule is 5x+-4
L(which is length) is equal to 42 divided by width which is 6. so the equation is L=42/6
You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
