Question

What are reasons A, B, and C in the proof?

Prove: (4 · 3)l + (2 · 4)l = 20l

Statements Reasons
(4 · 3)l + (2 · 4)l = (4 · 3)l + (4 · 2)l A. _________________
= 4(3l + 2l) B. _________________
= 4(5l) Addition
= (4 · 5)l C. _________________
= 20l Multiplication

Answer 1

Answer:

A. Commutative property

B. Associative and distributive properties.

C. Associative property.

Step-by-step explanation:

We proceed to present which reason are utilized by supporting procedure:

1) $(4\cdot 3) \cdot i +(2\cdot 4)\cdot i$ Given

2) $(4\cdot 3)\cdot i +(4\cdot 2)\cdot i$ A. Commutative property

3) $4\cdot (3\cdot i+2\cdot i)$ B. Associative and distributive properties.

4) $4\cdot (5\cdot i)$ Addition.

5) $(4\cdot 5)\cdot i$ C. Associative property.

6) $20\cdot i$ Multiplication/Result.
