Answer:
x=2.65
Step-by-step explanation:
First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:
[tex]4x-5*2.5=14[/tex]
This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:
[tex]4x-5=5.6[/tex]
Next, add 5 to both sides:
[tex]4x=10.6[/tex]
Then divide both sides by 4:
[tex]x=2.65[/tex]
