Answer:
The correct option is;
90 degrees counterclockwise rotation
Step-by-step explanation:
The coordinates of the preimage before rotation = K(17, -12)
The coordinate of the image of the preimage after rotation = K'(12, 17)
Therefore, the rotation transformation, transforms, the preimage (x, y) to the image (-y, x), which is equivalent to a rotation of 90 degrees counterclockwise
Answer:
The width of a rectangle is: w = x+3
Step-by-step explanation:
Given
The length of rectangle = l = 4x
The area of rectangle = A = 4x² + 12x
To determine
The width of rectangle = w = ?
We know that the formula of the area of the rectangle is
substitute A = 4x² + 12x and l = 4x in the equation to determine the width w of the rectangle
4x² + 12x = w×4x
w = [4x² + 12x] / [4x]
Factor 4x² + 12x: 4x(x+3)
w = [ 4x(x+3) ] / [4x]
w = x+3
Therefore, the width of a rectangle is: w = x+3
