Answer:
x= 3 and x= -3
Step-by-step explanation:
x^2 -9 = 0

(x+3)(x-3)
If x+3=0, then x= -3
If x-3=0, then x= 3
The circumference is 12.56cm and the area is 12.56cm
Answer: 0.457

multiply 1 by 5, and get 5.
5 × 7 = 35.
fraction: 21/35 and 5/35
Subtract the numerators
21 − 5 = 16 = 16/35
Now we need to simplify the fraction that we have.
17 is larger than 16. So we're done reducing numbers.
