It is a diagnal line that goes through (0,0) and (1,1) and has a slope of 1
Step-by-step explanation:
Hello,
Assume x the smallest side.
y the third side
z the largest side
z=2x-4
y=10+x
x+y+z=86
==>x+(10+x)+(2x-4)=86
==>4x=86-10+4
==>x=20, y=30 and z=36
7 because 7x3= 21 and 21 + the 7 cats comes to an equal 28
