(a)
2x + 10 ← factor out 2 from each term
= 2(x + 5)
(b)
5x - 15 ← factor out 5 from each term
= 5(x - 3)
(c)
8x + 6 ← factor out 2 from each term
= 2(4x + 3)
(d)
12x - 8 ← factor out 4 from each term
= 4(3x - 2)

Answer:
929
Step-by-step explanation:
For every 11 children, 7 will have homes and 4 will not.
The fraction of children without homes is 4/11.
The number of children without homes is
4/11 × 2556 = 929
Check:
The number of children with homes is 2556 - 929 = 1627
With/Without = 1627/929 = 7.005/4 ≈ 7/4
OK.
