What is 6.3-2(1.5c+4.1)

ASHA 777 [7]

$Expand\;-2\left(1.5c+4.1\right)$
$\mathrm{Distribute\:parentheses\:using}: \:a\left(b+c\right)=ab+ac$
$\;a=-2,\:b=1.5c,\:c=4.1$

$Simplify\;-2\cdot \:1.5c-2\cdot \:4.1 \ \textgreater \ \mathrm{Multiply\:the\:numbers:}\:2\cdot \:1.5=3$
$-3c-2\cdot \:4.1$

$\mathrm{Multiply\:the\:numbers:}\:2\cdot \:4.1=8.2 \ \textgreater \ -3c-8.2 \ \textgreater \ 6.3-3c-8.2$

$\mathrm{Subtract\:the\:numbers:}\:6.3-8.2=-1.9 \ \textgreater \ -3c-1.9$

Hope this helps!
