Mrs. Bosnjak 9.1 is not working. I can not post a comment

# data[].attributes.body
thanks tyler makes sense

You would subtract 15 on both sides then prime factor 15 and get the square root of 15

# data[].attributes.body
don't have an answer for your question...but

how do you do B? I'm at x squared =15 but i

forgot the last step

# data[].attributes.body
I know its a little late , but on 11 part

c I got to the factoring part and cant

figure it out from there.

I figured that since AB and BC are congruent, then AC is twice as long as AB, so I got the ratio 1:2

# data[].attributes.body
I just saw you type that, so it is probably the same for all of us.

# data[].attributes.body
Bo, the way it works for mine is that I can see new posts while people are typing them, I think it may be the same case for you

# data[].attributes.body
I think that because they are congruent, you would set AB as one and then AC as it is in relation to AB.

# data[].attributes.body
how do you do problem 10 part b?

# data[].attributes.body
If you get the x variables and the

y variables on the opposite sides

of the equal sign you can factor

them

I'm stuck on #20…

How do you simplify it?

I apologize if this is not on the topic of homework, but I am keeping this open while doing other things and am wondering if i must refresh the page to see new posts or if it will automatically update itself. I am not trying to go off topic, but it would be nice to know this information in the future.

I may be wrong but I believe they are referencing the places of the ratio, with a/b and c (5)/d. In this case it would be D as the last proportional, but my theory is theoretical, and is not based upon an equation.

Nate, you need to factor top and bottom using

the product-sum method. You can't cancel the x^2

on top and bottom. There should be 2 parentheses on

the top and 2 on the bottom. I'll tell you that the top

factors to (x-3)(x-4)

How is # 21 done? I have simplified down to

-7x+12

-16

# data[].attributes.body
Start by dividing both sides by y to get that on the bottom

How do you set up problem 19?

I don't under stand how to solve 4c. I am at the point of ax=5b... what do I do next
