Area of the label is calculated as diameter*PI*height
So if height of tomato can is 3 times the can of tuna: hTOM=3*hTUNA
Diameter of a tomato can is three times smaller so: dTOM=dTUNA÷3
so Area of a tomato can label= A=(dTUNA÷3)*PI*3*hTUNA
A=dTUNA*PI*hTUNA
and the area of a tuna can label=
A=dTUNA*PI*hTUNA
So, the label areas are the same.

Answer:
The scale factor of dilation is 2.
Step-by-step explanation:
From the given information it is notices that the vertices of preimage are A(1, 4), B(3, 4), C(3, 1), and D(1, 1). The vertices of image are A'(2, 8), B'(6, 8), C'(6, 2) and D'(2, 2).
The scale factor is the ratio of distance of a image of a vertex from the center of dilation and distance of the vertex from the center of dilation.
The center of dilation is origin. So, the scale factor is
.... (1)
Distance formula:
Now, put these values in equation (1).
Therefore the scale factor of dilation is 2.

Answer:
Correct answer: (2 x - 1) (x + 2)
Step-by-step explanation:
Given:
2 x² + 3 x - 2 = ( ) · ( )
2 x² + 3 x - 2 = 2 · ( x² + (3/2) x - 1) = 2 ( x² + 2 · x · (3/4) + (3/4)² - (3/4)² - 1)
2 x² + 3 x - 2 = 2 · ( (x + (3/4))² - (9/16) - 1) = 2 · ((x + (3/4))² - (9/16) - (16/16))
2 x² + 3 x - 2 = 2 · ((x + (3/4))² - (25/16)) = 2 · ((x + (3/4))² - (5/4)²)
2 x² + 3 x - 2 = 2 · (x + (3/4) - (5/4)) · (x + (3/4) + (5/4)) =
2 · (x - (2/4)) (x + (8/4))
2 x² + 3 x - 2 = 2 · (x - (1/2)) (x + 2) = (2 x - 1) · (x + 2)
2 x² + 3 x - 2 = (2 x - 1) · (x + 2)
