Zepler [3.9K]

Answer:

10(2+3)

Step-by-step explanation:

We are given that

Ice=20 lb

Cup=30

We have to find the expression which shows the greatest common factor using distributive property of 20 and 30.

We know that distributive property of integers a,b and c

a\cdot(b+c)=a\cdot b+a\cdot c

20=2\times 10

30=3\times 10

10(2+3)=10\times 2+10\times 3

Hence, the highest common factor of 20 and 30=10

Expression:10(2+3)
