Answer: [tex]-24.4x-24[/tex]
Step-by-step explanation:
Given the following expression:
[tex]9.6x+3[/tex]
In order to triple it, you must multiply it by 3:
[tex]3(9.6x+3)[/tex]
Now, to simplify it, you must apply the Distributive Property:
[tex](3)(9.6x)+(3)(3)=28.8x+9[/tex]
The exercise indicates that you must subtract it from this expression:
[tex]4.4x-15[/tex]
So, the subtraction have this form:
[tex](4.4x-15)-(28.8x+9)[/tex]
Therefore, subtracting both expressions, the expression obtained is:
[tex]=4.4x-15-28.8x-9=-24.4x-24[/tex]
