Step-by-step explanation:
First, transform 8 feet and 10 feet into inches so we can work with the same measurements
8 * 12 = 96 in
10 * 12 = 120 in
Next find the patio rectangle area.
96 * 120 = 11520 in^2
Now find the paving block area
4 * 8 = 32 in^2
Now, find out how many paving blocks will go into the patio rectangle area.
11520 / 32 = 360
The minimum number is 360 paving blocks
The asnwer should be P^m-n
Answer: a = -2 and c = 7
Step-by-step explanation:
(this answer uses some basic calculus)
We know that 
, and since 
is a maximum of 
, then 
. That means 
, so 
. Then since 
, we have 
, so 
.
The problem is actually already factored for you. They are asking you to just set the equation to zero. Find the zeros.
