Answer:

d = all real numbers

Step-by-step explanation:

-9d-8= -4 (d + 2) - 5d

-9d - 8 = -4d - 8 - 5d

-9d - 8 = -9d - 8

0d - 8 = -8

0d = 0

d = all real numbers

Shenelle has 100100100 meters of fencing to build a rectangular garden. The garden's area (in square meters) as a function of th
Step2247 [10]

Answer:

<h2>25metres</h2>

Step-by-step explanation:

Given the area of the garden in terms of the width modeled by the equation A(x) = -(x-25)²+625 where x is the width of the garden. The side with that will produce the maximum garden area is occurs at when d[A(x)]/dx  = 0

Given A(x) = -(x-25)²+625

d[A(x)]/dx  =-2(x-25) + 0

Since d[A(x)]/dx  = 0

-2(x-25) = 0

open the parenthesis

-2x+50 = 0

-2x = 0-50

-2x = -50

Divide both sides by -2;

-2x/-2 = -50/-2

x = 25metres

<em>Therefore the width of the garden that will produce the maximum garden area is 5metres.</em>

Sedbober [7]

The number of days Christen's book is overdue could be 22 according to options given.

The graph which represents the relationship between the number of days a book is overdue and the library fine charged is attached below :

According to the graph, a constant relationship exists between the number of days a book is overdue and the library fine charged when the Number of days book is  overdue is about 19 days and above such that the library fine charged stays the same at $10.

Since we are told that Christen's fine for returning the book is the same as the fine she would have paid if book was returned yesterday, then, the number of days Christen's book is overdue could be 20 days and above.

The only value above 20 from the options given is 22.

Hence, 22 is the valid answer.

Sarah bought 18 boxes of 65 pens at $12 a box. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. Find her total p
KonstantinChe [14]

Answer:

$108

Step-by-step explanation:

1 box = $12

18 boxes = 12×18 = $216

Total = 18×65 = 1170 pens

Cost price, Cp = $216

3 = $1

378 = 378/3 = $126

1170-378= 792 pens remaining

4 = $1

792 = 792/4 = $198

Total selling price, sp = 126+198 = $324

Profit = Sp - Cp = 324 - 216 = $108
