This is an equation that demonstrated the word problem. 8x=72. 8 represents the constant rate of candy bar's she sell each day. X represents the number of days it will take her to sell all the candy hard, and 72 is the number of candy bar's she needs to sell.
It will take Danielle 9 days to sell 72 candy bar's because 9*8=72.

Answer:
Population density = 
Step-by-step explanation:
The attached figure shows the dimension of an island.
Population density is equal to total population per unit land area.
Firstly we will find the area of the triangle using Pythagoras theorem as follows :
H is Hypotenuse, B is base and P is perpendicular
Area of triangle is given by :
Hence, the population density is .
Answer: B sorry if im wrong
Step-by-step explanation:
Answer:
110 ft
Step-by-step explanation:
The length of fencing is four times the perimeter of one garden.
The formula for the perimeter of a rectangle is
P = 2l + 2w
The total perimeter for all four rectangles is
P = 4× (2l + 2w) = 8l + 8w
Data:
l = 9¼ ft
w = 4½ ft
Calculation:
P = 8l + 8w = 8×9¼ + 8×4½ = 72⁸/₄ + 32⁸/₂ =(72 + 2) + (32 + 4) = 74 + 36 = 110 ft
The total length of fencing is 110 ft.
