All the dimensions of a parallelogram were multiplied by the same factor. If the area of the parallelogram went from 3 square centimeters to 12 square centimeters, the dimensions of the parallelogram were multiplied by what?

The answer is 2

Step-by-step explanation:

The dimensions of the parallelogram are most likely 3 and 1, so if you multiply both by 2 you get 6 and 2, which equal 12 when multiplied together

ik how do do this just give me a few minutes and i will give it to

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
