Answer:
4000 sq inches
Step-by-step explanation:
A rectangle is given with sides 82 and 46 inches
We have to round off these dimensions to the nearest 10.
82 inches ~80 inches since 2 <5, we make it 0
Similarly 46 inches ~50 inches since 6>5
Now area
= length x width
=80(50)
=4000 square inches
Option 2 4000 sq inches is correct answer.
I mean im prob in a lower grade then you so i'd say b?
4x ≤ 12
x ≤ 3 <em>divided both sides by 4</em>
Graph: ←--------------------3 <em>(fill in the dot at 3 since it is "equal to")</em>
Interval Notation: (-∞, 3]
