I think the answer is the 2nd choice = 1 inch wide and 8 inches long because he's making a scale and it has to be simplified.
Hope this helped☺☺
Answer:
3x-9=2x+4
-2x -2x
x - 9 = 4
+ 9 +9
<h2>
x = 13</h2>
First isolate the variable into one side.
Then simplify like terms.
Hope this helps.
1 1/4 = 1 3/12 and 2/3 = 8/12
1 3/12 + 8/12= 1 11/12
Answer:
use logarithms
Step-by-step explanation:
Taking the logarithm of an expression with a variable in the exponent makes the exponent become a coefficient of the logarithm of the base.

You will note that this approach works well enough for ...
a^(x+3) = b^(x-6) . . . . . . . . . . . variables in the exponents
(x+3)log(a) = (x-6)log(b) . . . . . a linear equation after taking logs
but doesn't do anything to help you solve ...
x +3 = b^(x -6)
There is no algebraic way to solve equations that are a mix of polynomial and exponential functions.

Some functions have been defined to help in certain situations. For example, the "product log" function (or its inverse) can be used to solve a certain class of equations with variables in the exponent. However, these functions and their use are not normally studied in algebra courses.
In any event, I find a graphing calculator to be an extremely useful tool for solving exponential equations.
