Step-by-step explanation:
The phrases that can be represented as the algebraic expression, 3n - 3 are: <em>Option 3 and Option 5.</em>
Let's translate each of the given phrases to algebraic expressions in order to determine which of them can be represented as 3n - 3.
<em>Option 1:</em>
3 fewer than n is represented as, n - 3
<em>Option 2:</em>
difference between n and 3 is represented as, n - 3.
<em>Option 3:</em>
3 times n is 3n
3 fewer than 3n is represented as 3n - 3.
<em>Option 4:</em>
product of 3 and n is represented as 3n.
<em>Option 5:</em>
3 less than 3n is represented as 3n - 3.
Therefore, the phrases that can be represented as the algebraic expression, 3n - 3 are: <em>Option 3 and Option 5.</em>

We have that
solution is
x <-10 or x>=25
for
x < -10
the solution is the interval (-∞, -10)
and
for
x>=25
the solution is the interval [25,∞)
therefore
the solution for
x <-10 or x>=25
is
(-∞, -10) ∪ [25,∞)
<span>the solution is any value of x less than -10 or greater than or equal to 25</span>
