​

Answer 1

Answer:

210

Step-by-step explanation:

(-21) [(-4) + (-6)] = [(-21) x (-4)] + [(-21) (-6)]

= 84 + 126

= 210

Answer 2

Step-by-step explanation:

$\color{red}{ANWER}$

• (-21) [(-4)+(-6)]=[(-21) ×(-4)]+[(-21) (-6)]

$\color{red}{LHS}$

• (-21) [(-4)+(-6)]
• (-21) [-4-6]
• (-21) [-10]
• -21*-10
• 210 $\color{red}{eq(1)}$

$\color{purple}{RHS}$

• [(-21) ×(-4)]+[(-21) (-6)]
• [-21×-4]+[-21×-6]
• 84+126
• 210 $\color{purple}eq{(2)}$

eq $\color{red}{(1)}$ se and $\color{purple}{(2)}$ se

• $\color{red}{LHS}$ = $\color{purple}{RHS}$ (HENCE PROVED)
