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>

The value of a professional basketball player's autograph rose 40% in the last year. It is now worth $294.00.
ZanzabumX [31]
I'll assume you're asking for the initial price

Let's use x to represent it
The initial price plus 40 percent of that is $294

Let's write that out mathematically

x + (40/100)x = 294
x + 0.4x = 294
1.4x = 294
x = 210

The initial price is $210

Find all real numbers x such that<br> 3x - 4 &gt;5 and 8x - 19&lt;
Kazeer [188]

Answer:

x < 2 ∪ x > 3

Step-by-step explanation:

Rewrite 3x - 4 > 5 as 3x > 9.  This tells us that x must be greater than 3.

Rewrite 8x - 10 < 6.  Thus, 8x <  16 and x < 2.

The "solution set" is thus all real numbers to the left of 2 OR to the right of 3.
