Answer with step by step explanation

Given that,

a = 2

b = 3

c = 1

To solve these expressions you have to replace a, b & c with 2, 3 & 1 respectively.

Let us solve these expressions.

1) 2ab + 3bc + 5ac

( 2 × 2 × 3 ) + ( 3 × 3 × 1 ) + ( 5 × 2 × 1 )

12 + 9 + 10

21 + 10

31

2) 2 ( a + bc ) + 4 ( ab + ac )

2 × ( 2 + 3 × 1 ) + 4 ( 2 × 3 + 2 × 1 )

2 × ( 2 + 3 ) + 4 ( 6 + 2 )

2 × 5 + 4 × 8

10 + 32

42

Let me know if you have any other questions. :)
