Answer:
∴3 ( 5a - 2b + 3c) = 15 a - 6 b + 9 c
Step-by-step explanation:
The distributive property of multiplication over addition is
m( a + b + c) = m a + m b + m c where a , b, c are natural numbers and m is constant.
3( 5a - 2b + 3c) = 3 ×( 5 a) - 3 ×( 2 b) + 3 × (3 c)
= 15 a - 6 b + 9 c
∴3 ( 5a - 2b + 3c) = 15 a - 6 b + 9 c
