Answer 2

$\large\sf\underline{Given:}$

• l = 7

• m = 8

• n = 0

‎

$\large\sf\underline{To:}$

• Find the value of 2l - 3m - 4n + lmn

‎

$\large\sf\underline{Solution:}$

$\sf\:2l - 3m - 4n + lmn$

‎

• Let's substitute the given value in the expression

‎

$\sf➞\:2(7) - 3(8) - 4(0) + (7)(8)(0)$

‎

$\sf➞\:2×7 - 3×8 - 4×0 + 7×8×0$

‎

$\sf➞\:14 - 24 - 0 + 56×0$

‎

$\sf➞\:14 - 24 - 0 + 0$

‎

$\sf➞\:- 10 - 0 + 0$

‎

$\sf➞\:- 10 -\cancel{ 0 }+ \cancel{0}$

‎

${\sf{{\pink{➻\:-10}}}}$
