Answer:
x = -27
Step-by-step explanation:
(x+2)(1-x)=-4
subtract 2 from both sides: x(1-x)=2
simplify:x-2x=2
subtract: -x=2
switch the negatives
x=-2
The value of the digit is In the Thousands place
Answer:
Step-by-step explanation:
The the area of the rectangular pen be A = LW
L is the length
W is the width
Given
A = 3136ft²
3136 = LW..........1
Given the perimeter P = 2L+2W....... 2
From 1; L = 3136/W
Substitute into 2
P = 2(3136/W)+2W
P = 6272/W + 2W
In order to minimize the amount of material needed, then dP/dW = 0
dP/dW = -6272/W² + 2
0 = -6272/W² + 2
6272/W² = 2
cross multiply
6272 = 2W²
W² = 3136
W = √3136
W = 56ft
Since A = LW
3136 = 56L
L = 3136/56
L = 56ft
Hence the dimensions of the rectangular pen that minimize the amount of material needed is 56ft by 56ft
Answer:
Plz Brain -list the answer It takes effort tnx dear
Step-by-step explanation:
From given condition
equation of line is given as,
x*cos(α)+y*sin(α)=p
& as tanα= 5/12 so from Pythagoras theorem
sinα= 5/13
cosα= 12/13
⇒12x+5y=39
<h2>
⇒12x+5y−39=0</h2>
