To determine the factors of the terms in the expression (20a + 15ab + 24b), we can factor each term. The factors of (20a) are (4 \times 5 \times a), the factors of (15ab) are (3 \times 5 \times a \times b), and the factors of (24b) are (3 \times 8 \times b). Common factors among the terms include (3) and (b). Thus, any statements indicating these common factors or the individual factors of each term would be true.
