1. Given that (27 ^ (n + 3))/(81 ^ (p - 1)) = 3 , express p in terms of h.

Troyanec [42]

Answer:

p = 3/4n +3

Step-by-step explanation:

Expressing the given equation in terms of powers of 3, we have ...

(27^(n+3))/(81^(p-1)) = 3

(3^3)^(n+3)/(3^4)^(p-1) = 3^1 . . . . as powers of 3

3(n +3) -4(p -1) = 1 . . . . . . . . . . . . log base 3 (or, equate exponents)

3n +9 -4p +4 = 1 . . . . . . . . . . . . . eliminate parentheses

3n +12 = 4p . . . . . . . . . . . . . . . . add 4p -1

p = 3/4n +3 . . . . . . . . . . divide by 4

A cube shaped suitcase has a length of 3x + 2 units. What is an expression for its area of the

Hitman42 [59]

Answer:

$\huge\boxed{\sf 9x^2+12x+4 \ units^2}$

Step-by-step explanation:

Given that,

Length of cube = l = 3x + 2 units

$= l \times l\\\\= (3x+2)(3x+2)\\\\= 3x(3x+2)+2(3x+2)\\\\= 9x^2+6x+6x+4\\\\= 9x^2+12x+4 \ units^2\\\\\rule[225]{225}{2}$

I just need help doing (d). I don’t know how to do it. Brainliest will be donated to the best answer

Tasya [4]

Answer:

Step-by-step explanation:

We need to solve this equation by graphing. We need to find what roots will make our equation equal zero. This is the same as drawing a line

$y = 0$

and see what points intercepts both graphs.

According to the graph above, one root are between 0 and 0.5 and the other are between 4 and 4.5.

We can find it actual value by solving it

$- 1 + \frac{9}{2} x - {x}^{2} = 0$

$- {x}^{2} + \frac{9}{2} x - 1 = 0$

Apply Quadratic Formula, we get

$\frac{9 + \sqrt{65} }{4}$

and

$\frac{9 - \sqrt{65} }{4}$

Which gives us approximately

x=4.27 and 0.23
