Ok so in order to do these, you need to make the bases the same. Since 3^2 is 9, you can make that side of the equation look like 3^2(x+5). Now, you have 3^x=3^2(x+5). Since the bases are the same, you can drop those. Your equation will now look like x=2(x+5). All that is left to do now is solve. x=2x+10 -> -10=x

Answer:
r = 100(
- 1 )
Step-by-step explanation:
Given
A = P(1 +
) ← divide both sides by P
= 1 +
( subtract 1 from both sides )
- 1 =
( multiply both sides by 100 )
100 (
- 1) = r
