The answer is 18 because to find the perimeter you have to add length+width+width+length so we know that the length is 25 so we add 25+25 which is 50. then we subtract 86-50 which is 36. so we do 36 divided by 2 which gets us 18. Hope this Helps! :)

The solution of the system of equations is the point (-3,0)
Answer: 
Explanation:
Follow PEMDAS in reverse to undo what's happening to x.
We first add 1 to both sides, then divide both sides by 5 to fully isolate x.
Refer to the steps below to see what I mean.

The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.
The solution set for x is anything -3 or larger.
If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}

Answer:</h2>
<u>The value of </u><u>p :M/9m</u>
<h2>Explanation:</h2>
As we have been given value of M
Value of M=9pm
So we can find value of p from here by simple mathematics rule
M=9pm
divide both side with 9m so
M/9m=9pm/9m
we get value of p so M/9m=p.
we can write it as p=M/9m
