If the third side is 12 (the sum of 5 and 7), we don't really have a triangle, since the 5-unit and 7-unit sides add up to 12 and lie on the third side (of length 12).
Since triangle ABC is acute, all its angles are between 0 and 90 degrees. So the third side can be 12 but not greater. The smallest possible length of the third side is 2, since 5 + 2 = 7.
<h2>Answer: -2</h2><h2 /><h3>Step-by-step explanation: When subtracting positive numbers, count to the left. When subtracting negative numbers, count to the right.</h3>
So you know that 1 cubic foot is equal to 80 pounds. So, the first point would be (1,80). You can find the other points by multiply 80 by a number, and when I did that, I got (2,160) and (3,240) too.
