Answer 1

$\bf\huge\pink{Answer}$

$\bf\huge{Given}$

$\implies \bf{m= -2}$

Answer -1

$\bf \implies \: 1) m - 2$

$\implies= -2( - 2)$

$\bf \implies -4$

Answer -2

$\bf \implies2) 3m - 5$

$\implies3 × (-2) - 5$

$\implies(-6 )- 5$

$\bf \implies- 11$

Answer -3

$\bf \implies \: 3) \: 9 - ( 5m )$

$\implies 9 - 5 ×( -2 )$

$\implies 9 - ( -10 )$

$\implies- 19$

Answer -4

$\implies\bf 4) 3m² - 2m$

$\bf{ \implies3 × ( -2 )² - 2 × ( -2 )}$

$\implies3 × 4 + 4$

$\implies12 + 4$

$\bf\implies 16$

Answer -5

$\bf \implies \: 5) 4m² + 3$

$\implies4 × ( -2 )² + 3$

$\implies4 × 4 + 3$

$\implies16 + 3$

$\bf \implies 19$
