Write 20 + 24 as a product using the GCF, 4, as one of the factors.

Which expression show 20 + 24 with 4 as a factor of each term?
1. (4x5) + (4x6)
2. (4x10) + (4x12)
3. 4 + (10x12)

The product of 20 + 24 using the GCF 4 as one of the factors is:

4 * (5 + 6) = 4 * 11 = 44

Therefore, the expression that shows 20 + 24 with 4 as a factor of each term is:

(4 * 5) + (4 * 6) = 20 + 24 = 44

So, the correct expression is option 1: (4 * 5) + (4 * 6)

now write the sum as a product using the GCF as one of the factors

20 + 24 = (4x5) + (4x6)
= ? (5+?)

20 + 24 = 4 * (5 + 6) = 4 * (5 + 4 + 2) = 4 * [(5 + 4 ) + 2] = 4 * (9 + 2) = 4 * 11 = 44

Therefore, the sum of 20 and 24, written as a product using the GCF 4 as one of the factors is 4 * (5 + 6) or 4 * (5 + 4 + 2).
