<span>x = length cm
y = width cm
---
y = 3
xy = area
xy = 1035
x*3 = 1035
x = 1035/3
x = 345
so the answer is 345</span>
Answer: 
Step-by-step explanation:
You need to set up two cases (Positive case and negative case) and solve for "x".
- POSITIVE CASE IF: 
- NEGATIVE CASE IF: 
Therefore, the solution is:
Answer:
Step-by-step explanation:
Answer:
d = log 38/log31
d = 1.06
Step-by-step explanation:
31 ^ d = 38
Take log of both sides since the exponential equation have different base (always)
d log 31 = log 38
d = log 38 / log 31
d = 1.58 / 1.491
d = 1.06.
We can actually check to see if this is correct.
Substituting d = 1.06
31^ 1.06 = 38.092
(You see, that's approximately correct)
