Answer: 3(5)+3(1) =18
Step-by-step explanation:
Hi, to answer this question we have to apply distributive property:
The distributive property allows you multiply a sum by multiplying separately each addend and then add the products.
In this case we have to multiply each addend (5 and 1) by three, and then add the results.
Mathematically speaking:
(5+1)3
3(5)+3(1)
15+3
18
