The answer will be -2-11r. Because you distribute the negative symbol (-) among the numbers in the parenthesis.
Step-by-step explanation:
a.c=2πr
c=2x3.142x50
c=100x3.142
c=0.03142
b.c=2πr
286=2x31/7xr
286=62r/7
286x7=62r
2002=62r
2002/62=r
32.3=r
r=32.3
1) x+2/x+3 = 4/5
2) 5x+10 = 4x+12 (cross multiply)
3) x+10 = 12
4) x=2
