Answer: B
Step-by-step explanation:
When you factor an expression, you want to take out a factor of the numbers and variables.
Since this expression is a bit hard to factor as itself, we can FOIL the answers to see the correct expressions.
(4x-5)(4x-5)
16x²-20x-20x+25
16x²-40x+25
10/16 because you multiply 8x2 to get sixteen, the denominator you need. So whatever you do to the denominator, you do to the numerator. So 5x2 is 10. 10/16
A)=14 meters because 3.5 times 4 is 14
b)=4 meters because circles don't have any sides
c)=a would give her more space to plant because 14 is bigger than 4
