Since
and
, we have

So, the equation becomes

The solutions to this equation are 4 and -5/2, so I'm afraid there's a typo in your question.
Answer:
359
Step-by-step explanation:
6x3+18
18 to the second power is 324
10x3=30
30+5=35
324+35=359
The perimeter without the diagonal is 4*120 = 480
That covers the outside of the field
The diagonal is 120 *

= 169.7 yd
480 + 169.7 = 649.7 yd total of fencing
3,7,11,15,19,23,27,31
32 = 8th term.
The common difference is +4
Answer:
4 hours
Step-by-step explanation:
72+12x=120 and when you isolate x you get x=4
