Expressions and Equations
A fencing company uses 4 planks of wood for one section of fencing, 7 planks
for two section, and 10 planks of wood for three sections. The fence sections
are represented using the toothpicks shown. Determine how many planks
would be used to create 5 sections of fencing.
Find a pattern in the table.
Then fill in the number of
planks that would be in 4
and 5 sections of fencing.
