How would the expression x-9 be rewritten using Difference of Squares?
1 answer:
Answer:
Step-by-step explanation:
(x+3)(x-3)
x squared and -9 are both square numbers.
the square root of x^2 is x
the square root of -9 is 3. so you just need to write (x+3)(x-3)
you can check by expanding the brackets and the middle x terms should cancel out

The equation that you should use to solve this is (13 + 1/4) - (6 + 2/3) = 6 and 7/12
Cone Volume = (PI * radius^2 * height) / 3
3 = (PI * radius^2* x) / 3
radius^2 = 9 / (PI * x)
radius = square root (9 / (PI * x))
The numbers could be 6, 12, 24.
