Answer:
you want to isolate x so just add 16 to the right side (-4)
so -16 + x = -4
+16 +16
x=12

Starting with a different number changes the diagram because if you started with any other number, you would get different results.
The smallest perimeter is 72.44 inches. The longest side of an acute triangle measures 30 inches. The two remaining sides are congruent, but their length is unknown. As much as possible, the sum of the length of the two remaining side must be greater than the other side. Given the side is 30, then the sum of the two remaining sides should be greater than 30 inches.
Answer: 16.
Explanation: The answer is 16 because 960 divided by 15 is 64. Lets say 64 is the rectangular prism is a square now without height. Since it is a square that means it is equal on all sides. So 64 is all of the sides combined if you divide 64 by 4 (Squares have 4 sides) it is 16. Meaning each individual side is 16. I hope this helped, if you can please make me the brainliest.
