Answer:
fondo
Step-by-step explanation:
A = LW
A = 72
L = W + 1
72 = W(W + 1)
72 = W^2 + W
W^2 + W - 72 = 0
(W + 9)(W - 8) = 0
W + 9 = 0
W = -9......extraneous solution...does not work here
W - 8 = 0
W = 8 <==
L = W + 1
L = 8 + 1
L = 9
so the width (W) is 8 ft and the Length is 9 ft
Answer:
Number of plain cookie boxes sold = 785 boxes
Step-by-step explanation:
Given: Cost of a chocolate chip cookie box = $1.25
Cost of a plain cookie box = $0.75
Total number of boxes sold = 1585
Total cost of the sold boxes = $1588.75
Let, number of plain cookie boxes sold = x
Number of chocolate chip cookie boxes sold = 1585 - x
So,
Total cost = total cost of the sold plain cookie boxes + total cost of the sold chocolate chip cookie boxes
$1588.75 = x ($0.75) + (1585 - x) ($1.25)
1588.75 = 0.75 x + 1981.25 - 1.25 x
0.5 x = 392.5
Therefore,
<u>Number of plain cookie boxes sold: x = 392.5 ÷ 0.5 = 785 boxes</u>
draw a rectangle around it:
the widest part is from about -3 to 2 which is 5 units wide
height is from 3 to -4, which is 7 units
5*7 = 35
the top and bottom are angled so you can subtract a little for that
so I would estimate around 32 square units
8, 3, -2, -7
basically
you have to figure how to get from one term to the other. so in this case, to get from 8 to 3, you have to minus 5. and same again to get from 3 to -2, you again have to -5.
so the first past of the answer is -5n.
then after that, you have to figure out how to get from -5, to the first term of your sequence. so you have to add 13, in this case.
your answer would then be
<h2>
<em><u>
-5n + 13</u></em></h2>
