Please Help Me!!! Its Homework

1. How can writing expressions show how quantities are related?

2. Rewrite the expression 12x + 8 to find an equivalent expression. Show three possible expressions. What do the rewrite expressions among quantities?

3. A rope is used to make a fence in the shape of an equilateral triangle around a newly planted tree. The length of the rope is represented with the expression 9x + 15.

a. Rewrite the expression to represent the three side lengths of the rope fence

b. What is the length of one side?

4. The expression (x - 0.35x) represents 35% off the cost of an item x. How is this equivalent to multiplying x by 065x?

Please take your time on this its worth 100%

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.

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.

3a. 15 + 9x

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
