Answer:
17
Step-by-step explanation:
2+5(8-5)
2+(5×8)-(5×5)
2 +40-25
42-25

X^2 - 6x = 20
x^2 - 6x + 9 = 20 + 9
(x - 3)^2 = 29
x - 3 = (+-) sqrt 29
x = 3 (+-) sqrt 29
x = 3 (+-) 5.39
x = 3 + 5.39 = 8.39 <=
x = 3 - 5.39 = - 2.39 <=
The missing fraction would be
since it is exactly in the halfway between
5-32
10-64
15-96
1 more to make 16. 5 divided into 32 equals 5.7
Total 101.7
Answer:
Step-by-step explanation:
The volume of the aquarium is 2880 in^3.
Height of the aquarium is 4 inches
The base of the aquarium is rectangular in shape.
Let the length be L
Let the width be W
The length of the rectangle is 4 inches more than twice the width. It means that
L = 2W + 4
The volume of the aquarium is expressed as L × W × H
Therefore
L × W × H = 2880
Since H = 4,
4LW = 2880
LW = 2880/4 = 720
LW = 720 - - - - - - - -1
Substituting L = 2W + 4 into equation 1, it becomes
W(2W + 4) = 720
2W^2 + 4W - 720 = 0
W^2 + 2W - 360 = 0
W^2 + 20W - 18W- 360 = 0
W(W +20) - 18(W + 20) = 0
W-18 = 0 or W + 20 = 0
W = 18 or W = -20
Since the width cannot be negative, it is 18 inches
L = 720/W = 720/18
L = 40 inches
Length is 40 inches
Width is 18 inches
