@mathstudent55 can you help?
OpenStudy (mathstudent55):
Same idea as before. Multiply two segments of one chord and set equal to the product of the two segments of the other chord:
2(3x - 2) = 5x
OpenStudy (mathstudent55):
Now you need to solve that equation for x.

hmmm im having trouble

First, you need to distribute the 2 on the left side.
OpenStudy (anonymous):
yeah so 6x = 4
OpenStudy (mathstudent55):
An example of the distributive property os:
2(4x - 8) = 2*4x - 2*8 = 8x - 16
Now apply the distributive property to
2(3x - 2)
OpenStudy (mathstudent55):
There is no equal sign inside the left side. The left side is simply
2(3x - 2)
OpenStudy (anonymous):
oops i meant 6x - 4

Good, now that is equal to 5x, so write that.
OpenStudy (anonymous):
6x - 4 = 5x
OpenStudy (mathstudent55):
Now subtract 5x from both sides.
OpenStudy (anonymous):
is the final answer -1x = 4?
OpenStudy (anonymous):
i mean -4

it cant be
OpenStudy (anonymous):
1x - 4
OpenStudy (mathstudent55):
You are very close. You are correct that there is a 4 on the right side.
Look on the left side. You have 6x on the left side and you subtracted from it 5x. What is 6x - 5x?
OpenStudy (mathstudent55):
6x - 4 = 5x
6x - 5x = 4
OpenStudy (anonymous):
is it 1x?

so 1x = 4
OpenStudy (anonymous):
so is 3 the final answer?
OpenStudy (anonymous):
no because 5 + 3 is not 9
OpenStudy (anonymous):
ughh im getting frustrated lol
OpenStudy (mathstudent55):
1x = 4 means x = 4. x = 4 is the final answer
