Answer:
7.8
Step-by-step explanation:
The diameter is the full length across a circle. The radius is always half the diameter. if you divide 15.6 by 2 (to get half), we get 7.8. If this does not answer the question, let me know so I can edit
Given the quadratic equation:
Using the general solution for quadratic equations:
From the problem, we identify:
Then:
And the solution set is:
![\lbrack\frac{-5-3\sqrt{5}}{2},\frac{-5+3\sqrt{5}}{2}]](https://tex.z-dn.net/?f=%5Clbrack%5Cfrac%7B-5-3%5Csqrt%7B5%7D%7D%7B2%7D%2C%5Cfrac%7B-5%2B3%5Csqrt%7B5%7D%7D%7B2%7D%5D)
1. A. Add 6 to both sides to solve.
2. D. If you simplify the a terms you will get 6 = 7 which is never true.
3. A. Subtract 1.2m from both sides and then divide to solve.
4. B. If you simplify you get 7 = 7 which is always true.
5. D. Distribute the 2 and then add the 24 to both sides. Then divide to solve.
6. A. Simplify the right side and then divide all by two. Then add 16 to both sides and divide by 4.
7. 3y - 2
