56 is you answer you need.
Answer:
4
Step-by-step explanation:
The rule of dilation is
This means that each distance QX' is equal to
where X is initial point and X' is its image after dilation.
Since QA=6, then

The computation shows that the value of the expression is 2.3.
<h3>How to illustrate the information?</h3>
It should be noted that the information given is illustrated as:
2.3(4.5-3 1/2)
This will be solved thus:
2.3(4.5-3 1/2)
2.3 ( 4.5 - 3.5)
= 2.3 (1)
= 2.3 × 1
= 2.3
Therefore, the value is 2.3
