Plug -2 into the equation where t is, so 4 - 3( - 2 ). Multiply 3 and -2 first which is -6. 4 - (-6) is 4+6=10
The circumference is 6.28, and the area is 3.14. So, the circumference is greater than the area (circumference > area).
2(x-7)/3=-2
3*2(x-7)/2*3=-2*3/2
x-7=-2*3/2
x-7=3*-1
x+(7-7)-7-3
x=7-3
x=4
Idk but try using a^2 +b^2=c^2
