What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Expression is,
⇒ √- 25 + 2√- 9
Hence, We can change it into monomial in term of i as;
⇒ √- 25 + 2√- 9
⇒ √- 5² + 2 √- 3²
⇒ 5i + 3 × 3i
⇒ 5i + 9i
⇒ 14i
Since, i² = - 1
Thus, The correct expression is,
⇒ 14i

It means that x∈ (-∞, -12.8 ) ∪ (7.8, +∞ ).
Answer: C) x ≠ 7
Thank you.
If inequality 5x + x² > 100, then x is not equal to 7.
The given inequality looks like you have a quadratic inequality that we have to solve,
5x + x² > 100
To determine which values of x will not satisfy this inequality,
We can use algebraic manipulation.
We can rewrite the inequality as,
x² + 5x - 100 > 0
Then, we can use the quadratic formula to find the roots of the equation, which are x = (-5 ± √(425)) / 2.
x ≈ -12.8 or 7.8
It means that x∈ (-∞, -12.8 ) ∪ (7.8, +∞ ).
Hence, x ≠ 7
