Yes it's A cos that's the correct answer
4inches = 1/3 of a foot (4inches x 3 = 12 inches) - so she can cut 3 out of each foot
1 yard = 3 feet - so she can cut 3 x 3 = 9 out of each yard
18 x 9 = 162 pieces
B. 33.5 is your answer
First you want to add 12+4 because it is in parentheses
8.5+16x2-7
Then you multiply 16 by 2
8.5+32-7
Then you add 8.5 to 32
40.5-7
Then you subtract 7 from 40.5 giving you your answer
33.5
Substitute the x with 5
-(5)2 + 4(5) - 10 = 0
