Answer 1

Respuesta:

-819.6

Explicación paso a paso:

$6\left(3\left(-9+4\left(5.2-9\right)\right)-2\left(40-8\right)\right)\\3\left(-9+4\left(5.2-9\right)\right)\\=3\left(-9-15.2\right)\\=3\left(-24.2\right)\\=-3\cdot \:24.2\\=-72.6$

$=6\left(-2\left(40-8\right)-72.6\right)\\2\left(40-8\right)\\=2\cdot \:32\\=64$

$=6\left(-64-72.6\right)\\=6\left(-136.6\right)\\=-6\cdot \:136.6\\=-819.6$
