SA = ? 
<span>r = 2x - 1 </span>
<span>h = 3x </span>

<span>Then, </span>

<span>SA = 2π(2x - 1)² + 2π(2x - 1)(3x) </span>
<span>==> 2π(4x² - 4x + 1) + 6πx(2x - 1) </span>
<span>==> 8πx² - 8πx + 2π + 12πx² - 6πx </span>
<span>==> 20πx² - 14πx + 2π units² </span>

5/6w+21=-1/3(2w-9).
oksian1 [2.3K]
I believe this question logically tells us to find the value of w. The two equations are already equated. Since there is 1 unknown and 1 equation, the system is solvable. The solution is as follows:

5/(6w+21) = -1/3(2w - 9)
5/(6w+21) = -1/(6w - 27)
Cross multiplying the terms:
5(6w - 27) = -1(6w +21)
30w - 135 = -6w - 21
30w + 6w = -21 + 135 = 114
36w = 114
w = 114/36
w = 19/6 or 3.167

8-3(x - 5) + 2x + 3 how do I solve this ​
schepotkina [342]

Answer:

The answer is -x+26.

Step-by-step explanation:

First you distribute the -3 into the parthensis and you get -3x+15. You write the whole expression again plus the -3x+15 you got from the distributing part so 8-3x+15+2x+3. You combine the like terms so the x with the x and the numbers with the numbers. From there you get the answer of -x+26. I hope this helps you! If you need more clarification or more help please type it in the comments below. Thanks!
