Question

Evaluate the following expressions if  a=2 , b=3, and c=1. Show your complete solution.

Answer 1

1. 2(2)(3) + 3(3)(1) + 5(2)(1) = 31
2. 2(2 + (3)(1)) + 4((2)(3) + (2)(1)) = 42

Answer 2

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
