Answer:
5)12/x
6) a number increased by 10
7) three times a number decreased by 5
8) 6 times a number increased by 2
Step-by-step explanation: "a number" refers to a variable.
4/52 = 1/13 ... there are four 5 cards in a deck and 52 cards in a standard deck so 4/52 !
Take first derivative of area function and set it to zero
da/dx=24 - 2x=0
Now it is set to zero add -2x to both side
24 - 2x = 0
24 = 2x
Now divide by 2 in both sides
12 = Width
Your width now is 12
Plug 12 into you equation like this:
24 (12) - 12^2= A
288 - 144 = A
144 = Area
144 feets is the maximum area using the width 24
The domain is -5, -4, 1, 2, 4
