Answer:
Step-by-step explanation:
The given function is
We want to find all values of x for which:
f(x) is greater than or equal to 14.
This implies;
Subtract 13 from both sides;
By definition of the absolute value function,
Divide through the first inequality and and reverse the inequality sign:

Step-by-step explanation:
Given
Shape: Parallelogram PQRS
Required
Find all possible values of x
<em>Every parallelogram have parallel and equal opposite sides;</em>
From the given parameters, one can easily deduce that PQ and SR are opposite sides;
This implies that
Substitute values of PQ and SR
Subtract 3x from both sides
Rearrange
Now, we have a quadratic equation;
Expand the above expression
Factorize
or
Solve for x in both cases

<em>But x can't be negative;</em>
<em>So, the possible value of x is </em>
