Question

⑤ 20z - 8 =
20: 1, 2, 4, 5, 10, 20
8: 1, 2, 4, 8
⑥ 36a + 16b =
36:
16:

Explanation:

Step1: Factor problem 5, find GCF

GCF of 20 and 8 is 4.
$20z - 8 = 4(5z - 2)$

Step2: List factors for problem 6

Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 16: 1, 2, 4, 8, 16

Step3: Factor problem 6, use GCF

GCF of 36 and 16 is 4.
$36a + 16b = 4(9a + 4b)$

Answer:

1. $20z - 8 = 4(5z - 2)$
2. Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

Factors of 16: 1, 2, 4, 8, 16
$36a + 16b = 4(9a + 4b)$
