Answer:
hello : x = (ln(20))/3
Step-by-step explanation:
4 + e3x = 24?
e3x = 24 - 4
e3x = 20
3x = ln(20)
x = (ln(20))/3
The answer to this equation is 3
The value of x would be 6.5 because if you add 1 to 6.5 you get 7.5 and 7.5 multiplied by 4 is 30
Note that 49b^2 - 256 = 0 is the difference of two squares. Thus, 49b^2 - 256 = 0 can be re-written as
(7b)^2 - 16^2 = 0, which factors into (7b+16)(7b-16)=0.
Solving for b: 7b+16=0 becomes b = -16/7, and
7b-16=0 becomes b = 16/7.
As expected, this 2nd order equation has 2 solutions.
