Answer:
Yes, parallelogram OABC is a rectangle.
Step-by-step explanation:
The vertices of a parallelogram are O(0,0), A(-4,1), B(-3,5) and C(1,4).
A parallelogram is a rectangle if its any two adjacent sides are perpendicular to each other.
product of slopes of two perpendicular lines is -1.
Formula for slope is
Using the formula we get
It means OA is perpendicular to AB.
Since two adjacent sides are perpendicular, therefore the given parallelogram OABC is a rectangle.
Answer:
Divide both sides by l.
Step-by-step explanation:
The equation that we have to solve in this problem is
where
A is the area
l is the length
w is the width
Here we want to solve the equation for w, the width. It means that we have to isolate this variable.
In order to do so, we proceed as follows:
1) We divide by l on both sides:
2) We simplify l on the right side, so we get:
So, we have solved for w.
Therefore, the correct answer is
Divide both sides by l.
