Answer:
A) 
Step-by-step explanation:
The polynomial factored is equal to the area of the algebra tiles. This means the quadratic is

After writing out each tile as a term, combine like terms to simplify. This ia the quadratic.
You need to first set up the equation:
It would look like 90 divided by 360 multiplied by the given
circumference which is 72 cm.
So 90 / 360 x 72
Simply the fraction above, it will give us:
¼ x 72
So the answer would be 18 cm that is the length of DE (minor
arc)
Answer: 17
2^2 is 4
45/9 is 5
Multiply 4•5 to get 20
Subtract 3
