C. all horses that are diagnosed with enteroliths
5 x 6 + 7? Is that what the answer is, I didn't get the question towards the end. :)
Answer:
5.1
Step-by-step explanation:
14^-2*1000
Perimeter = 2*(length +width)
perimeter = 2*(3x + (3x +(2x+6)))
.. = 2*(3x +3x +2x +6)
.. = 2*(8x +6)
perimeter = 16x +12
If x=3, the perimeter is 16*3 +12 = 60 inches.
