Answer: The required simplified form is [tex]-30r+15.[/tex]
Step-by-step explanation: We are given to simplify the following expression :
[tex]E=20(-1.5r+0.75).[/tex]
To simplify the above expression, we must multiply 20 with each term within the bracket.
The multiplication is as follows :
[tex]E\\\\=20(-1.5r+0.75)\\\\=20\times(-1.5r)+20\times 0.75\\\\=-30r+15.[/tex]
Thus, the required simplified form is [tex]-30r+15.[/tex]
