i don't understand
Step-by-step explanation:
Answer:
Option C.
Step-by-step explanation:
The given logarithmic equation is
It can be written as
![[\because log_ax=y\Leftrightarrow x=a^y]](https://tex.z-dn.net/?f=%5B%5Cbecause%20log_ax%3Dy%5CLeftrightarrow%20x%3Da%5Ey%5D)
Now, to check whether is a true solution or not. Substitute in the LHS of given equation.
![[\because log_aa^x=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20log_aa%5Ex%3Dx%5D)
Hence, is a true solution because 
.
Therefore, the correct option is C.
Answer:
The flower garden width would be 6 ft
Step-by-step explanation:
A = 12 ft^2 = x(x + 4) becomes:
x^2 + 4x - 12 = 0, or (by completing the square) x^2 + 4x + 4 - 4 - 12 = 0
Thus, we have (x + 2)^2 - 16 = 0, or (x + 2)^2 = 16
Taking the square root of both sides yields x + 2 = ±4.
In this context only a positive x value makes sense: x = 2 + 4 => x = 6.
The flower garden width would be 6 ft. The other dimension would be 6 - 4, or 2, ft.
Answer:
(x^2 + 3)(x + 1).
Step-by-step explanation:
x^3 + x^2 + 3x + 3
= x^2(x + 1) + 3(x + 1)
= (x^2 + 3)(x + 1).
