Think of it this way. Let's say t= one. 1+8 is 9. Your answer is 9t. Think of a variable without a number as one.
We are given the rule for the set,
M= {x | x is an integer and -2 < x < 1}In words, this set translates to numbers that are integers and greater than -2 but less than 1.
The actual elements of the set are
M = { -1, 0}
There are only two elements.
The tree is 820 inches tall using the similarity of triangles.
To get the height of the tree, we will use the properties of similar triangles expressed as:

- Note that 1 foot = 12inches
- 7ft = 84in and 82ft = 984in
- h is the required height of the tree. Simplify the equation above to get the height "h" and replace feet with inches;

Hence the tree is 820 inches tall using the similarity of triangles.
