Answer: 8a-28 b+15c

Step-by-step explanation:

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

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

4(2a)= 4\times2 a = 8a               (1)

7(-4b)=7\times-4b= -28 b           (2)

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

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

The standard form of the given expression :

8a-28 b+15c
