8a + -28b + 15 x c  

just combine like terms basically.

Answer: [tex]8a-28 b+15c[/tex]

Step-by-step explanation:

The given expression : [tex]4(2a) + 7(-4b) + (3 \times c \times 5).[/tex]

To write the above expression in standard form , we will simplify each term as

[tex]4(2a)= 4\times2 a = 8a[/tex]               (1)

[tex]7(-4b)=7\times-4b= -28 b[/tex]           (2)

[tex](3 \times c \times 5)= 3\times5\times c= 15c[/tex]        [using commutative property]         (3)

Using (1) , (2) and (3) , we get

The standard form of the given expression :

[tex]8a-28 b+15c[/tex]
