Answer:
Divide both sides by-2
Use the distributive property
Step-by-step explanation:
If you divided both sides by -2, you would get n + 3 = -6.5. Then you would have to subtract 3 from both sides, so n would be -9.5.
However, if you used the distributive property, you would get -2n - 6 = 13. Then you could add 6 to both sides and get -2n = 19. Finally, to solve for n, you would divide both sides by -2 to get n = -9.5.
Hope this helps!
Answer:
10
Step-by-step explanation:
area=√3/4×a^2
100√3 = √3×a^2
a^2 = 100
a=10
side = 10
