Rectangle a measures 12 cm by 3 cm. rectangle b is a scaled copy of rectangle a. select all of the measurement pairs that could be the dimensions of rectangle b.
a. 6 cm by 1.5 cm
b.10 cm by 2 cm
c. 13 cm by 4 cm
d.18 cm by 4.5 cm
e.80 cm by 20 cm

A, D, and E

Step-by-step explanation:

The ratio between the sides of the rectangle is 12/3 = 4. In a scaled copy of rectangle A, the ratio between the sides needs to be 4 too.

For answer A the 6/1.5 = 4, has the same ratio therefore is a scaled version of rectangle A

For answer B the 10/2 = 5, it does not has the same ratio therefore is not a scaled version of rectangle A

For answer C the 13/4 = 3.25, it does not has the same ratio therefore is not a scaled version of rectangle A

For answer D the 18/4.5 = 4, has the same ratio therefore is a scaled version of rectangle A

For answer E the 80/20 = 4, has the same ratio therefore is a scaled version of rectangle A

hope this is what you were asking for!

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
