Answer: 3
Step-by-step explanation:
You can answer this question by using the equation
(8+x)(7+x)=110
The x represents the width, as we do not know the area. If you simplify the equation, it becomes 56+15x+x2=110.
If you move all the terms to the left side, and rearrange it, it can become x^2+15x-54=0
This can be simplified into (x-3)(x+18)=0
This equation makes it so that x is either 3 or -18. It is not possible for a width to be -18, so the width must be 3.

Step-by-step explanation:
joint porbability formula
0.23*0.73*0.74 = 0.124246
20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.
