<span>Shortest side = x, Longest Side = 4x-1, third side = 18
Equation is x + (4x-1) + 18 = 42 so 5x-1 = 42-18=24 and 5x=25 so x = 5, longest side = 4(5)-1=19, third side=18
Add all 3 (5+19+18) to get 42</span>
I believe it would be 12.16
In the first problem you are given a formula (y = 3x), along with a table.
From the data in the table, find the slope of the linear equation that relates x and y in that data.
Then compare the two slopes. Which is the greater? the smaller?
