Question

18 X [7+(-3)] = [18x7]+ [18 x(-3)]​

Answer 1

Answer:

$18\left[7+\left(-3\right)\right]=\left[18\cdot \:7\right]+\left[18\left(-3\right)\right]\quad :\quad \mathrm{True}$

Step-by-step explanation:

$18\left[7+\left(-3\right)\right]=\left[18\cdot \:7\right]+\left[18\left(-3\right)\right]$

$18\left(7+\left(-3\right)\right)$

$=18\left(7-3\right)$

$=18\cdot \:4$

$=72$

$\left(18\cdot \:7\right)+\left(18\left(-3\right)\right)$

$=18\cdot \:7-18\cdot \:3$

$=126-18\cdot \:3$

$=126-54$

$=72$

$72=72$

$\mathrm{Both\:sides\:are\:equal}$

$\mathrm{True}$
