Question 310356: The email given earlier is not correct :( I am sorry here is the right one.
You are given an exteded ratio that compares the lengths of the sides of the triangle. find the lengths of all unknown sides.
DE:EF:DF is 4:5:6 DE=16 EF=y DF=y+4
I tried 4(16)+ 5(y) + 6(y+4) but the answer in the back of the book isn't the same answer I get. I have had no instruction in Geometry since the beginning of April as I haven't been going to regular school. I have been in a homebound program and never got anything with Geometry until now. I hope you can help me. I have a final to take and I haven't done anything in any chapters past 4.

You are given an extended ratio that compares the lengths of the sides of the triangle.
find the lengths of all unknown sides.
DE:EF:DF is 4:5:6 DE=16 EF=y DF=y+4
:
We can do it this way
:
let x = the multiplier
then the three sides will be 4x, 5x, 6x
using side 1, DE, find x
4x = 16
x = 16%2F4
x = 4 is the multiplier
:
Side 2: 4(5) = 20 (EF)
side 3: 4(6) = 24 (DF)
:
We don't are care what y is, but you can find it if desired:
:
EF: y=20
DF: y + 4 = 24
