Answer:
57+132+96 = 285
360-285= 75
B = 75
Step-by-step explanation:
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.

Step-by-step explanation:
Answer:
The length is 8 inches and the width is 3 inches
Step-by-step explanation:
Let w represent the width.
The length can be represented by 2w + 2
Use the area formula, A = lw, and plug in the area and the expressions for the length and width:
A = lw
24 = (2w + 2)(w)
Simplify and solve for w:
24 = 2w² + 2w
2w² + 2w - 24
Divide everything by 2:
w² + w - 12
Factor:
(w + 4)(w - 3)
Set equal to 0 and solve for each factor:
w + 4 = 0
w = -4
w - 3 = 0
w = 3
Since the width cannot be negative, the width has to be 3.
Next, find the length by plugging in 3 as w:
2w + 2
2(3) + 2
= 8
So, the length is 8 inches and the width is 3 inches
