Answer:
x^2 -5x +14 = 10^(2x +4)
Step-by-step explanation:
The relationship is ...
log(a) = b ⇔ a = 10^b
__
Using this with a=x^2-5x+14 and b=2x+4, we have ...
x^2 -5x +14 = 10^(2x +4)
_____
<em>Additional comments</em>
In plain text, the exponent needs parentheses, because superscript formatting is not available to tell what is and isn't part of the exponent.
The base of "log" is assumed to be 10 in high school algebra. In the larger world, "log" is often used in place of "ln" to mean the logarithm to base 'e'.

The one solution is approximately x = −1.32505947996.
Answer:
b=9
Step-by-step explanation:
18/24=3/4
3/4=b/12
cross product
4*b=3*12
4b=36
b=36/4
b=9
3x + 4y = 12
To find x subtract 4y from both sides
3x = 12 - 4y
Then divide all terms by 3
3x/3 = 12/3 - 4y /3
So, x = 4 - 4/3y
