Step-by-step explanation:
(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)
B is correct
6(3+2)
3+2= 5
5x6= 30
18+12= 30
30=30
T=d/r
plug in your numbers and divide then you have your answer.
