We are given
[tex] (-7c+8d)0.6 [/tex]
we can use distribute property
Distributive property:
[tex] (A+B)C=A*C+B*C [/tex]
so, we can write it as
[tex] (-7c+8d)0.6=-7c*0.6+8d*0.6 [/tex]
[tex] (-7c+8d)0.6=-7*0.6c+8*0.6d [/tex]
now, we can multiply terms
and we get
[tex] (-7c+8d)0.6=-4.2c+4.8d [/tex]..............Answer
