You can rewrite this equation as "f - g - 1". That's all that I see that you can do with this.
N + 3 simply means we are adding 3 to the number before. An example of such of a pattern would look like this:
3, 6, 9, 12
4, 7, 10, 13
5, 8, 11, 14
11. brother = ???
???- 12 = 14
14+12=26
brother is 26.
12. 21.35 - 8.95 = 12.4
cost of colored pencils = $12.40
13. 37- 8 = 29
14. $95 - $73 = $22
Answer:
No, It is not a right triangle
Step-by-step explanation:
For it to be a right triangle, the hypotenuse would be equal to the sum of the legs when squared.
Use the pythagorean theorem-
8^2+12^2=15^2
64+144=225
208=225
Since they aren't equal, it is not a right triangle.
