A. 2.5 or if 5/2 isn't "5 divided by 2" 5/2
B. x7/3 = 1 (write in number form?)
C. x = 1/22 = 0.045
I hope these are the correct answers for you!
It's either 15, 17 or 18. Anything higher would make angle AC much longer than seen in the image.
Answer:
Done below!
Step-by-step explanation:
(x - root)
(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

If the perimeter is 26, and the width is 4, then add 4 twice, to get 8. Then subtract 8 from 26 to then get 18, you have two lengths, so divide 18 by 2. Your answer is 9.
To check add 4+4+9+9 = 26.
hope it helped! :)
