The solution to the answer is as follows:
We have...
y = (x + 9)(x + 6)
Then...
<span>y = (x + 5(9)) (x + 5(6))
</span>
= (x + 45) (x + 30)
<span>Hence, the x-intercepts are -45 and 30.

To have the same cost at both companies, the number of stickers will have to be 40
Company A :
Design Fee = $30
Costvper sticker = $0.80
Company B :
Design Fee = $14
Cost per sticker = $1.20
Let the number of stickers = p
Total cost of company A = 30 + 0.80p
Total cost of company B = 14 + 1.20p
For the cost to be the same :
Company A = Company B
30 + 0.80p = 14 + 1.20p
Collect like terms :
30 - 14 = 1.20p - 0.80p
16 = 0.40p
Divide both sides by 0.40
p = 16/0.40
p = 40 stickers
Therefore, to have the same price, 40 stickers will have to be ordered.
