# Thread: geometry question?

1. ## geometry question?

the base of an isosceles triangle has length 8. what can you say about the lengths of the legs?

2. Their length is greater than 4.

3. find the value of x?

1. 7x+3=10x-9

2. 4x+6=6x-3

4. You are supposed to post new question in new threads....but I'll answer it anyways.

1.) $7x+3=10x-9$

Add 9 to both sides:

$7x+12=10x$

Subtract 7x from both sides:

$12=3x$

Divide both sides by 3:

$x=4$

2.) $4x+6=6x-3$

Add 3 to both sides:

$4x+9=6x$

Subtract 4x from both sides:

$9=2x$

Divide both sides by 2:

$x=\frac {9}{2}$

5. ## You can say

that their measures are equal...as well as
