To start off Quantities can be compared in terms of "more", "less", or "equal". (definition)
<em>1. In expressions, there is always a quantity of something, whether an object being weighed, or an object being counted. To show how quantities are related you would have something to equal to, less than, or more than. which is being compared to one another.</em>
2. (12 * x) + 8 //// 8+ 12x //// 8 + (12 * x). This is all based on communitive property, and just switched the numbers around. they all equal to the same answer.
<u><em>3a. 15 + 9x</em></u>
<u><em></em></u>
<u><em>3b. the length would be 9. This is because an equilateral triangle has 3 of the same length of sizes, and x represents the length of each side. making x=3</em></u>

Answer:
B
Step-by-step explanation:
we know that a=b and b=c than we can write that a=c because a equal b . in the position of b we can write a . second question that b=c Infront of b we can write a because there is a= b show its answer is a=c
This equation is called an expression. I know this because there are variables instead of numbers.
