Question

Simplify using commutative and distributive property:

$(-8)\times 3-2\times 8=.....$

• A. $8$
• B. $40$
• C. $-8$
• D. $-40$

Answer 1

The correct option is D $-40$

$(-8)\times 3-2\times 8$
$=(-8)\times 3-8\times 2$ ($\because$ commutative property)
$(-8)\times 3-(-8)\times 2$
$=(-8)\times [3+2]$ ($\because$ distributive property)
$=(-8)\times 5$
$=-40$.
