16
Answer:
The correct answer is a) 16
Step-by-step explanation:
To find this first distribute the interior negative to both terms in the parenthesis.
9 - {x - (7 + x)}
9 - {x - 7 - x}
Now simplify the like terms.
9 - {-7}
Now distribute the negative once again.
9 + 7
And complete the indicated operation.

Answer is 264 cm^2
Step-by-step explanation:
2/5 * (n - 1) < 3/5 * (n + 1)
2/5 * n - 2/5 < 3/5 * n + 3/5
- 2/5 - 3/5 < 3/5 * n - 2/5 * n
- 5/5 < 1/5 * n
- 1 < 1/5 * n /*5
- 5 < n
n > - 5
n = x
The correct result would be B) <span>x > - 5.</span>
