Hi,
Let assume x the 3th side.
x<12+7==> x<19
12<x+7==>x>5
So 5<x<19==> 5+7+12<x+7+12<19+7+12
==>24<x<38
Answer d.
step 1 has incorrect justification
Consecutive even integers are 2 apart
they are
x and x+2
sum is 110
x+x+2=110
2x+2=110
minsu 2 both sides
2x=108
divide both sidedse by 2
x=54
x+2=56
the numbers are 54 and 56
Answer:

2 X < 11 and
x < 5.5
So all of the values in the set would have to be less than 5.5
