To find the perimeter you would add up all of the sides, so:
5x - 2 + 3x + 4 + x - 10
Now you combine the like terms
5x + 3x + x = 9x
-2 + 4 - 10 = -8
So your final answer is C) 9x - 8. I hope this helps!
Answer: The answer equals 0
Cancel something
we cancel x's
multiply 1st equation by 5 and 2nd by 7 and add them
-35x-30y=-5
<u>35x-28y=7 +</u>
0x-58y=2
-58y=2
divide both sides by -58
y=-1/29
sub back
5x-4(-1/29)=1
5x+4/29=1
minus 4/29 from both sides
note, 1=29/29
5x=25/29
divide bot sides by 5 (or times 1/5)
x=5/29
(5/29,-1/29)
