Triangles ? abc and ? def are similar. find the lengths of the sides of ? def, if ab=2 cm, bc=3 cm, ca=4 cm, de=1.5 cm.

where is the figure

i would need to see the dot plot : )

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20
