It says to simplify so number 3 would be 12

Number 4 is

Number 5 is
You’d have to solve your equations!
they’d be the same when x=-56
and when x=-56 they’d BOTH equal -27
Similarities:
Have a consistent change for every interval can be represented as functions of a variable points lie on a line.
Differences: linear equations represent all solutions to all x values, whereas arithmetic sequences pick integer spacing
The length of the base is 32.6
3.3 + 3.3 = 6.6
Subtract 6.6 from 71.8 : 65.2
Divide that by 2 : 32.6
