Add all the ratio components.

3+10+12 = 25

Divide that from 400, the perimeter.

400/25 = 16

Multiply that with 12, the largest ratio component.

You get 192, which is your answer.

Hope this helps!

Answer:

x = -18

Step-by-step explanation:

x - (-5)= - 23

you would do the opposite of -5 which is positive 5 and you would add 5 to the negative 5 to cancel out that -5 and add 5 to the -23 which gives you -18 so x = -18

Hope this helps!
