Question

If F=x+4 and BC=3x+6, what is FE

Answer 1

F is the midpoint of AB and E is the midpoint of AC

Answer 2

@RED123url

Answer 3

can you help please

Answer 4

you know that FE=1/2 (BC) right?

Answer 5

@nincompoop can you help please

Answer 6

Use similar triangles. Observe that ∆ABC is similar to ∆AFE

Answer 7

FE/BC = AE/AC = AF/AB = 1/2
FE/BC = 1/2
FE = 1.5x + 3

Answer 8

What do you mean by F = x + 4. F is a point.

Answer 9

It's in terms of x, because a point cannot take a value. My answer is FE = 1.5x + 3. How did you get x = 1?

Answer 10

Then I have no idea. Sorry...
