Sagot :
Answer:
The answer is "-21.6".
Step-by-step explanation:
In the given question, there is a mistype in the equation so, its correct equation can be defined as follows:
Given:
[tex]\to (-9) (2 \ and \ 2/5) = (-9)(2+ \frac{2}{5})[/tex]
[tex]= (-9 \times 2 )+ (-9\times \frac{2}{5})\\\\= (-18 )+ ( -\frac{18}{5})\\\\= -18 -\frac{18}{5}\\\\= \frac{-90-18}{5}\\\\= - \frac{108}{5}\\\\=- 21.6[/tex]
OR
[tex]\to (-9)(2+ \frac{2}{5})= (-9) (\frac{10+2}{5})[/tex]
[tex]= (-9) (\frac{12}{5})\\\\= (-9) (2.4)\\\\=-21.6[/tex]
