2x = 3
x = 3/2
x = 1.5

With 2^2x=2^3 x would equal 2. You simplify both sides of the equation and then isolate the variable

3. You have decided to wallpaper your rectangular bedroom. The dimensions are 12 feet 6 inches by 10 feet 6 inches by 8 feet 0 i

Shalnov [3]

Answer:

B. 5 rolls

Step-by-step explanation:

The areas of the room, not including the ceiling, are discriminated as follows:

Longer walls: $(12.5\times8)\times2=200ft^2$ (6 inches equals one foot)

Shorter walls: $(10.5\times8)\times2 = 168ft ^ 2$ (6 inches equals one foot)

Window area: $(4\times3)\times2 = 24ft ^ 2$

Door area: $(7\times3) = 21ft ^ 2$

Area that will be effectively covered:

Total area to wallpaper: $200 + 168 -24 -21 = 323ft ^ 2$

Amount of paper needed: $323\times1.1 = 355.3ft ^ 2$

$30in = 24in + 6in = 2ft + 0.5ft = 2.5ft.$ That is, the area of a roll of paper is $2.5\times30 = 75ft ^ 2$

Number of rolls needed:

$\frac{355.3}{75} = 4.73$ rolls

Let the number be n.

Then:

n^2 + (1/n)^2 = 82/9; find n. Find the LCD; it is 9n^2.

Mult all 3 terms by 9n^2:
82*9n^2
9n^4 + 9 = (82/9)(9n^2) => 9n^4 + 9 = ------------
   9
Then 9n^4 - 82n^2 + 9 = 0

I used my graphing calculator to find that n = 3.

Let's check: is 3^2 + (1/3)^2 = 82/9?
Is 9 + 1/9 = 82/9?
Is 81 + 1 = 82? YES. So, n=3 is a solution.
