Hello from MrBillDoesMath!
Answer:
x = 7/8
Discussion:
3[x + 3(4x – 5)] = 15x – 24 =>
3x + (3*3)(4x-5) = 15x - 24 =>
3x + 9*(4x) - (3*3)*5 = 15x - 24 =>
3x + 36x - 45 = 15x - 24 => (add 24 to each side)
3x + 36x - 45 + 45 = 15x - 24 + 45 =>
39x = 15x + 21 => (as 45-24 = 21)
39x-15x = 21 => (subtract 15x from both sides)
24x = 21 =>
x = 21/24 = -7/8

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
Step-by-step explanation:
please answer this question urgent
Integration Formula:
Integrate each term:
Altogether this becomes:
Your limits are 1 and 2. Substitute both numbers into the equation and minus them from each other.
x = 2:
-
x = 1:
![[tex]\frac{\frac{1}{3} - \frac{1}{2}-5 }{ \frac{1}{2}+2}](https://tex.z-dn.net/?f=%5Btex%5D%5Cfrac%7B%5Cfrac%7B1%7D%7B3%7D%20-%20%5Cfrac%7B1%7D%7B2%7D-5%20%7D%7B%20%5Cfrac%7B1%7D%7B2%7D%2B2%7D)

x = 2:
-
x = 1: 
=
-1.212317928
Now convert all the answers to integers and see which one matches -1.212317928:
Because it's a negative number, we know it can only be A or B.
(A) = -1.212317928
(B) = -1.19047619
The answer is A: 
<h2>(A) - 3/2 = ln 4/3</h2>
Answer: 5 units
Step-by-step explanation:
To solve this you need to use the formula for Chord-Chord length. You need to know it, it is ab=cd. with this, we can plug numbers in.
a=30
b=x+1
c=2x-6
d=21
So our new equation is:
30(x+1)=21(2x-6)
30x+30=42x-126
156=12x
x=13
This isn't what the question is askign for though, it wants YZ
Which is A+B or 30+x+1 or 21+13=34.
YZ=34
