Remark
There are occasions where this is very handy to know. Use FOIL.
Solve
F: (First): x*y = xy
O: (Outside): x *(-9) = - 9x
I:(Inside): (-7)*y = - 7y
L:(Last): (-7)*(-9) = 63
Add the terms together
xy - 9x - 7y + 63 <<<< Answer
There are 5280 feet in one mile.
If you have one and two-thirds of a mile, you can divide 5280 by 3, multiply it by 2, and then add it to 5280.
This will give you an answer of 8800 feet in 1 2/3 miles
