Answer:
To find the perimeter of a quadralateral on a coordinate plane, use the distance formula to find the length of each side, and then add the lengths. By using this method, you can find the perimeter accurately.
Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
-72 = 3(-4x - 8)
Step 2: Solve for <em>x</em>
<u>Distribute 3:</u> -72 = -12x - 24
<u>Add 24 to both sides:</u> -48 = -12x
<u>Divide both sides by -12:</u> x = 4
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-72 = 3(-4(4) - 8)
-72 = 3(-16 - 8)
-72 = 3(-24)
-72 = -72
