I assume you mean A = k^2 + 19k + 60. If the values of k are natural numbers then the area must be A = (k + 15)(k + 4) which is the factored form of the quadratic. The only statement about the rectangle that can be made is that the long side of the rectangle is 11 more than the short side. Lets say that k = 10 then the dimensions of the rectangle are 25 and 14.

If g(x) = 3x − 4, what is the value of g−1(g(13))?
Vsevolod [243]
The function g(x) = 3x-4 is a linear function. Therefore the inverse does exist (which is also linear)

Because we have an inverse, this means we can use the rule 
g^{-1}(g(x)) = x

Replace x with 13
g^{-1}(g(x)) = x
g^{-1}(g(13)) = 13

The answer is choice D

Answer:  x = 2

<u>Step-by-step explanation:</u>

2^{2x}-2^x-12=0\\\\\text{Let u = }2^x\\\\u^2-u-12=0\\(u-4)(u+3)=0\\\\u-4=0\quad and\quad u+3=0\\u=4\qquad and\quad u=-3\\\\\text{Substitute u with }2^x\\2^x=4\qquad and \quad 2^x=-3\\2^x=2^2\quad and\quad \text{not possible}\\\boxed{x=2}

********************************************************************************

Answer:  x = 0

<u>Step-by-step explanation:</u>

3^{2x}+3^{x+1}-4=0\\\\3^{2x}+3^x\cdot3^1-4=0\\\\\text{Let u = }3^x\\u^2+3u-4=0\\\\(u+4)(u-1)=0\\\\u+4=0\quad and\quad u-1=0\\u=-4\qquad and\quad u=1\\\\\text{Substitute u with }3^x\\3^x=-4\qquad and\quad 3^x=1\\\text{not possible}\ and\quad 3^x=3^0\\.\qquad \qquad \qquad \qquad \boxed{x=0}
