the answer is D-n is greater then or equal to nine.
because the red dot starts on nine and goes up its greater than nine and because its on nine its also going to equal it. I had a problem getting the signs messed up when I learned it but I remember the sign always eats the greater number. I hope this answer could help and I'm sorry if the answer is incorrect.
The solution of <span>0 = x2 − 5x − 36 is x = - 4 and x = 9

We know all the side lengths so can use law of cosines. a=90, b=55, and c=50.
2500=8100+3025-2(90)(55)cos(C)
cos(C)=.8712
C=arccos(.8712)=29.4 degrees
Answer:
26.75 or 26.75156923
Step-by-step explanation:
Circumference formula:
C =Лd
Diameter formula:
d=c/Л
Substitute C for 84 and Л for 3.14:
d=84/3.14
Solve for Diameter:
d=26.75
