Question

resolver utilizando la ley de los signos (7)(15)+(-20)(4)-(-6)(8)​

Answer 1

_____________________________________________________

LEY DE LOS SIGNOS ==> (+) (-)=(-) ; (+) (+)=(+) ; (-) (+)=(-) ; (-) (-)=(+)

_____________________________________________________

$\left(7\right)\left(15\right)+\left(-20\right)\left(4\right)-\left(-6\right)\left(8\right)$

$=105+\left(-20\right)\left(4\right)-\left(-6\right)\left(8\right)$

$=105-80-\left(-6\right)\left(8\right)$

$=105-80-\left(-48\right)$

$=25-\left(-48\right)$

$=25+48$

$=73$
