The formula of the surface area of the rectangular prism is equal:

where:
l - length
w - width
h - height
We have:
l = 5m
w = 8m
h = 9m
Substitute:
3 nickels and 1 quarter add to $0.40.
The person has 11 times that amount, so has 11 quarters and 33 nickels.
Answer:
Step 3
Step-by-step explanation:
By adding 104+34 and then 228+877, Then adding both of the results and finally subtracting the answer by one of the factors.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Explanation:
Which will be...
104+34=138
228+877=1,105
Then add them...
138+1,105=1,243
Finally, subtract your answer by one of the factors...
1,243-1,105
Which will result as 138. Which is also one of the factors you added earlier, that's basically what your looking fro when checking and subtraction and/or addition problem.
Use quotient rule to find y"
y" = [-(x-3)-(1-x)]/(x-3)^2 = 2/(x-3)^2
y" = -4/(x-3)^3
-4/(x-3)^3 > 0
(x-3)^3 < 0
x-3 < 0
x< 3
hope this help
