Answer:
no
Step-by-step explanation:
3 is the x coordinate/ integer and -4 is the y coordinate and the integer so it wouldn't make sense
x= 3 is a solution
and id you don't understand the first thing i said watch this
#1. 3, - 4
#2. x= - 4
#3. substitute/replace the x with what the x coordinate is
#4. it will be 3= - 4
#5. as you can see the numbers don't equal each other so it's a no solution
To find perimeter you add up all the sides so 5cm+6cm+17cm+8cm. This will get you 36cm.
