Answer:

x = 2

Step-by-step explanation:

Here's your solution

=> we know that tangents from a point to a common circle are equal

=> so, ST = SU

=> 7x - 3 = 5x + 1

=> 7x - 5x = 1 + 3

=> 2x = 4

=> x = 4/2

=> x = 2

hope it helps

Solve 4^x+2 = 12 for x using the change of base formula log base b of y equals log y over log b.

The value of x is 1.66

Step-by-step explanation:

Let use revise the rules of exponential and logarithmic equations

1. If y = $b^{x}$ , then $log_{b}(y)=x$

2. $log_{b}(y) = \frac{log(y)}{log(b)}$

Use the rules above to solve the problem

∵ $4^{x}+2=12$

- Subtract 2 from both sides

∴ $4^{x}=10$

change the exponential equation to logarithmic equation

∴ $log_{4}(10)=x$

∵ $log_{4}(10) = \frac{log(10)}{log(4)}$

∴ x = $\frac{log(10)}{log(4)}$

∴ x = 1.66

The value of x is 1.66
