Rectangle a has the length 12 and a width 8 rectangle b has length 15 and width 10. is rectangle a and scaled copy of b if so what is the scale factor?

Step-by-step explanation:

The ratio of length to width in each case is ...

 length : width = 12 : 8 = 3 : 2 = 15 : 10

Since the aspect ratio of the rectangles is the same, one could be a scaled copy of the other.

The scale factor of A from B is ...

   A/B = 8/10 = 4/5

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

what level of math? also i don't need to be paid if i can you.
