The expanded form of 15 is 10+5.
Answer:
8 * (9 - 2 -3) = 32
Step-by-step explanation:
8 * (9 - 2 - 3)
8 * (4)
32
The <em>correct answer</em> is:
|w-20| ≤ 0.12.
Explanation:
We first find the average of the two ends of the inequality:
(19.88+20.12)/2 = 40/2 = 20
This will be the number subtracted from w in the inequality.
Now we find the difference between this value and the ends:
20-19.88 = 0.12
20.12 - 20 = 0.12
This will be what our absolute value inequality ends with; the "answer" part, so to speak.
Since this inequality is written in compact form, it must be an "and" inequality; this means the absolute value inequality must be a "less than or equal to."
This gives us
|w-20| ≤ 0.12
You can solve this problem algebraically by representing each of the unknown values (the dimensions of the playpen or its length and width) with certain variables. Then, you represent the length in the terms of the width, as it is 20 feet longer than the length. What you may do next is substitute all of the parts of the equation that you've composed into the area formula for the rectangle, and then you can solve for the width and then for the length of the playpen, hence finding its dimensions.
