Simplify the product using foil.
(3x - 7 ) (3x - 5)
a. 9x² + 6x + 35
b. 9x² + 36x + 35
c. 9x²- 36x - 35
d. 9x² - 36x + 35

F) 3x*3x= 9x²
O) 3x*-5= -15x
I) -7*3x= -21x
L) -7*-5= 35
equation would be 9x²-36x+35

The answer to this is 27 ribbons bc first u have to convert 9 feet to inches which is 12*9=108in. Then since he uses 1/3 foot of ribbon to make each book mark ( u would know that 1/3 of a feet is 4 inches ) so u divided 108 by 4 which is 27 ribbons : )
