Answer:
Step-by-step explanation:
Note that 
.
Aha! We see a path to the solution!
We now know that our equation is actually 
.
We can divide both sides by 
to get 
.
By inspection or taking the logarithm base 2 of both sides, we see that 
.
So, the answer is 
and we're done!
Answer:
Step-by-step explanation:
No, because let’s say for example that something cost $100.00 so you take 20% (or $20) off of the 100 and you’re left with $80.00. Well then you have your 10% off coupon so you take 10% off of 80, which is 8 dollars. So now you’re at $72.00.
But if we just took off 30% from 100 originally, you would be at $70.00
So no it wouldn’t be the same. If you wanted to check the idea yourself just use different numbers and see if they match at the end.
Answer:
Option A
Step-by-step explanation:
To be considered skew lines, both must not intersect or be parallel.
If you let x represent the width of the rectangle, then you can write the equation for area as
.. x(2x +5) -63 = 0
This has positive solution x=4.5.
The rectangle is 4.5 meters by 14 meters.
