The solution to the expression is 12z + 42.
The expression and the missing properties are
- Distributive property
- Rewrite
How to use distributive property?
(7 + 2z)6 Given
= 6(7 + 2z) Re-write
= (6 × 7) + (6 × 2z) Distributive property
= 42 + 12z Multiply
= 12z + 42 Rewrite
Therefore, the expression (7 + 2z)6 when expanded is 12z + 42
