17. Have you learned that the products of the chord segments are equal?
Yes, it's just finding x that I'm having trouble with.
What equation did you write?
I will help you solve it.
I haven't written an equation yet. I really have a hard time with equations, I'm not very good with them :/
Do you see the two chords in your picture?
2x+3 and 4 are a chord, and 10 and x are the other chords, right?
Yes. So far so good. Do you know what a product is?
I don't think I do
A product is the answer to a multiplication problem. 4 times 3 equals 12. 12 is the product.
What is the product of 2x+3 and 4?
That's what I'm having trouble with, I can't figure that out :/
4(2x+3) have you heard of the distributive property?
It's been a while, that's why I'm pretty rusty with this stuff!
Distribute the 4 to the 2x and to the 3 What is 4 times 2x?
4 times 2x is 8x. What is 4 times 3?
Now the other chord. the two parts are 10 and x. what is 10 times x?
That is where I get lost, because I honestly have no idea :/
4(2x + 3) = 10 x 8x + 12 = 10x 12 = 2x 6 = x
And, the second question" Each of the measures (5,5,4) from the scale drawing will be multiplied by a factor of 6. That gives the square base the dimensions 5 by 5 and the pyramid a height of 24. V = 1/3 Bh where B is the area of the square base. V = 1/3 (30 * 30) 24 V = 7200 cubic feet
Directrix is right. I was about to simplify. :)
Thank you guys SO much for taking the time to explain everything to me, I really appreciate it!
