Answer:
5(5x+3)
Step-by-step explanation:
25x=5*5x
15=5*3
5*5x+5*3
Factor out the Common 5
5(5x+3)
13 you add both of the factors
14^(7x) = 17^(-8-x)
Take the log of both sides:
7x*log 14 = -(8+x)*log 17, or 7x^log 14 = -8*log 17 - x*log 17.
Grouping the x terms, we get x(7*log 14 + log 17)= -8*log 17
Then:
-8*log 17
x= -------------------------- (answer)
7*log 14 + log 17
Answer:
B. 
Step-by-step explanation:






400 - 3x = 163
Add 3x to both sides.
400 = 163 + 3x
Subtract 163 to both sides.
237 = 3x
237/3 = 79
