Answer:
All have same magnitude.
Step-by-step explanation:
Given that
Vector 1 = V+ (-W) = V - W
So the magnitude of vector 1, R₁
R₁ = V -W
For vector 2
Vector 2 = W - V = W - V
So the magnitude of vector 2, R₂
R₂ = V - W
For vector 3
Vector 3 = (-V) - (-W) = - V + W = W - V
So the magnitude of vector 3,
R₃ = W -V
So all have same magnitude.
Answer:
Area = units square.
Perimeter = 8y units.
Step-by-step explanation:
Area of a rectangle = length * width.
Perimeter of a rectangle = 2*(length + width).
It is given that length = y−2 units and width = 3y+2 units. To find the area and the area of the rectangle in terms of y, simply put the length and the width in the above area and perimeter equations.
Area = length * width = (y-2)*(3y+2).
Expanding the expression gives:
Area = 3y^2 + 2y - 6y - 4 = (3y^2 -4y - 4) units square.
Similarly,
Perimeter = 2*(length + width) = 2*(y-2 + 3y+2) = 2*4y = 8y units.
Therefore, the expression for the area and the perimeter of the given rectangle is () units square and (8y) units respectively!!!
