Step-by-step explanation:
The domain of f(x) is all values of x for which f(x) is defined.
For f(x) to be defined, the expression under the radical must be non-negative.
Therefore, the domain is x ≥ 0, or in interval notation, [0, ∞).
Answer:
(-67/3, -13/3)

Answer:
Step-by-step explanation:
1 = (20 x 70) + (70 x 20) = 1400 x 2 = 2800 squared meters
2 = 9.18 x 2 = 18.36 + 9.72 = 28.08 squared centimeters
3 = 9 x 4 = 36 + 6 + 3 = 45 squared units
2.5 still if you make it a fraction it would be 2 and 1 1/2 so you can't simplify that any more
Hmm they're both even numbers so maybe we can start by cutting each number in half.

18 and 48 had 2 as a common factor.
So factoring a 2 out of each number was the same as cutting each number in half. Try to do something similar with the 9 and 24. They each have something in common.
