Answer:
x>=-1, B
Step-by-step explanation:
1. distribute 2 to get 7+x <= 2x+6+2
2. simplify to get 7+x <= 2x+8
3. subtract 7 on both sides to get x<=2x+1
4. subtract x on both sides to get 0 <= x+1
5. subtract 1 on both sides to get x >= -1
B fits this description
I order to do this question, you need to put the 13 on the right side. So now you have x^2+12x+0=13. Now, take half of 12, and square it. Add this to both sides to get x^2+12x+36=49. Now factor the left side by putting the half of 12 into this blank to get, (x+_)^2=49. Final Answer is,
(x+6)^2=49.
