The sum (addition) of -2 and 3 times (3 ·) a number (n)
-2 + 3n
1. 2^6.
2. 2^3.
3. 3^7
4. 6x^4
5. 4x^2
6. 12n^5
7. 9x^2
To find the answer of these questions, add the exponents. If there is whole numbers in the problem, you have to multiply the numbers. For number 7, do 3^2 and x^2. Hope this helps!
1. remember all of them add up equal to 360 degree.
2. add all of them up together

3. combine like term then solve for Y
4. you will figure the arc measure of BC when you get answer for Y.
The range would be [-4, infinity) because range is the y-value. The lowest y-value is -4. The greatest y-value goes up to infinity.
