The awnser is A becuase 12/3=4
For #1 it's going to be proper because it's pretty specific, and for number two it's going to be all common because it's not citing anything specific.
Answer:
2x^3-23y^2+72-128
Step-by-step explanation:
its like when you just do two
do the first 2 first
(y-8)(y-8)
this is (y^2 -8y+y^2+16) simplify (2x^2-7y+16)
then add the other bracket
(2x^2-7y+16) (y-8)
2x^3-16x^2-7y^2+56y+16y-128 simplify
Answer:
I must sell more than 318 copies so my revenue is greater than my costs
Step-by-step explanation:
The cost function (C(x)) is divided in two: fixed costs and variable costs. In this case, we have both, the fixed costs are $3,500 that I will spent on advertising and the variable cost is the print cost that depends on the number of books i want to print. The cost function is:
C(x)= $3,500+$4x
The revenue function depends on the number of books I sell:
R(x)= $15x
If i want to know how many books I should sell to have a greater revenue than cost i must solve this inequality:
Revenue (R(x))>Cost (C(x))
$15x>$3,500+$4x
$15x-$4x>$3,500
$11x>$3,500
x>$3,500/$11
x> 318,18
I must sell more than 318 copies so my revenue is greater than my costs
Answer:
279 ft^2
Step-by-step explanation:
The area of a rectangle of length L and width W is A = LW.
Here, that area is (19.25 ft)(14.5 ft) = 279.125 ft^2, or approx. 279 ft^2
