Answer:
D. x^2 +14x + 40
Step-by-step explanation:
(x+4)(x+10)
x^2+10x+4x+40
x^2+14x+40
Let s represent the number of sales, and t the total pay
the equation to represent this situation is t = 2s + 50
so set t to 100, and solve for s
100 = 2s + 50
50 = 2s
25 = s
you need to make at least 25 sales
Answer:
2 years: 9 months
We know that, 1 year =12 months

24months
=
3months
8months
=8 months :3 months
Hence, 8 months: 3 months is the simplest form of 2 years :9 months
