3 to the power 2x+3 is subtracted by 9 which is equal to 2 times 9 to the power x+1 and is subtrcted by 6
Answers
Answer:
x = -0.5
Step-by-step explanation:
Here we have the sentence:
"3 to the power 2x+3 is subtracted by 9 which is equal to 2 times 9 to the power x+1 and is subtracted by 6"
The first part:
"3 to the power 2x+3 is subtracted by 9..."
This can be written as:
[tex]3^{2x + 3} - 9[/tex]
"... is equal to 2 times 9 to the power x+1 and is subtracted by 6"
[tex]3^{2x + 3} - 9 = 2*9^{x + 1} - 6[/tex]
Let's solve this for x.
First, we can add 9 in both sides:
[tex]3^{2x + 3} = 2*9^{x + 1} - 6 + 9 = 2*9^{x + 1} + 3[/tex]
We also know the relations:
[tex]a^n*a^b = a^{n + b}[/tex]
and
[tex](a^n)^m = a^{n*m}[/tex]
We can write the left part as:
[tex]3^{2x + 3} = 3^{2x}*3^3 = (3^2)^x*3^3 = 9^x*27[/tex]
And the right side as:
[tex]2*9^{x + 1} + 3 = 2*9^x*9 + 3 = 18*9^x + 3[/tex]
Then the equation becomes:
[tex]27*9^x = 18*9^x + 3[/tex]
Now let's move both terms with 9^x to the left side:
[tex]27*9^x - 18*9^x = 3\\[/tex]
[tex](27 - 18)*9^x = 3[/tex]
[tex]9*9^x = 3[/tex]
[tex]9^x = 3/9 = 1/3[/tex]
Now remember that:
Ln(a^b) = b*Ln(a)
Then if we apply the Ln( ) function to both sides, we get:
[tex]Ln(9^x) = Ln(1/3)[/tex]
[tex]x*Ln(9) = Ln(1/3)[/tex]
[tex]x = \frac{Ln(1/3)}{Ln(9)} = -0.5[/tex]
Please help!!! Confused.

Answer:
[tex] {x}^{2} + 11x + 30[/tex]
Step-by-step explanation:
Area is length x width
The length is
[tex](x + 6)[/tex]
The width is
[tex](x + 5)[/tex]
Multiply both using FOIL Method
[tex](x + 6)(x + 5)[/tex]
[tex] {x}^{2} [/tex]
[tex]6 \times x = 6x[/tex]
[tex]5 \times x = 5x[/tex]
[tex]6 \times 5 = 30[/tex]
Write in standform form
[tex] {x}^{2} + 6x + 5x + 30[/tex]
[tex] {x}^{2} + 11x + 30[/tex]

All sides of a right triangle are different lengths.
The shortest being the leg in which is opposite to the smallest angle on the standard right triangle (30 degrees). The side with the longest length is always the hypotenuse (point a-c).
Therefore, both answer a and b are eliminated considering two sides of the triangle have equivalent lengths.

Answers
Answer:
Step-by-step explanation:
P = 2b + a = 100
A = b * a
a = 100 - 2b
A = b(100 - 2b) = 100b - 2b^2
dA/db = 100 - 4b
100 - 4b = 0
b = 25
a = 50

the lowest elevation, in meters, in Florida?
Answers
Answer:
