Answer: Simplified form is [tex]-4.2a+5.6b[/tex]
Step-by-step explanation:
Since we have given that
[tex](-2.4a-1.8b)-(-3.8a-4.4b)+(2.0a+3.0b)[/tex]
We first gather the like terms together:
[tex](-2.4a-1.8b)-(-3.8a-4.4b)+(2.0a+3.0b)\\\\=(-2.4a-1.8b)+3.8a+4.4b+2.0a+3.0b\\\\=-2.4a-3.8a+2.0a-1.8b+4.4b+3.0b\\\\=-4.2a+5.6b[/tex]
Hence, simplified form is [tex]-4.2a+5.6b[/tex]
