Answer:
Step-by-step explanation:
Putting the values in F(x)=5x-1
= -6,-1,5,9
Range =highest -lowest =9--6
=15
I can't tell what the numbers are on the first one but you got the second one right, and the last one would be different it would be 24 I believe.
There are going to be two solutions because the "biggest" x is x^2 but you can factor to find what they actually are.
These are not similar. For them to be similar, they need to exist in proportion to each other for every single side. The ratio of the 12:9 sides is 4:3 when reduced. The ratio of the other 2 sides is 5:3. They all have to have the same ratio for them to be similar.
Lynn age: 7x+2. That's if you wanted an equation.
