Question

Verify informaly that "3*(5 2a)" and "3*2a*5 3*5". are equivalent using substatution

Answer 1

To verify the equivalence of two expressions, substitute a value for 'a' and compare the results and we can conclude that the two expressions are not equivalent.

Step-by-step explanation:

To verify that "3*(5 + 2a)" and "3*2a*5 + 3*5" are equivalent using substitution, we can substitute a value in for 'a' and compare the results.

Let's assume 'a' = 2.

Using the first expression: 3*(5 + 2(2)) = 3*(5 + 4) = 3*(9) = 27

Using the second expression: 3*2(2)*5 + 3*5 = 3*4*5 + 3*5

= 60 + 15

= 75

Since the results are different, we can conclude that the two expressions are not equivalent.
