Answer:
x = -3±sqrt( 5)
Step-by-step explanation:
(x + 3)^2-5=0
Add 5 to each side
(x + 3)^2-5+5=0+5
(x + 3)^2 = 5
Take the square root of each side
sqrt((x + 3)^2 )=±sqrt( 5)
x+3 = ±sqrt( 5)
Subtract 3 from each side
x+3-3 = -3±sqrt( 5)
x = -3±sqrt( 5)

Step-by-step explanation:
Answer: 14s - 7s/2 = 84
Step-by-step explanation:
Given that s is the length of the unknown side:
Area of the shaded region = 84
Area of rectangle - Area of triangle = 84
Area of rectangle = L * W
= 14 * s
= 14s
Area of triangle = ¹/₂ * base * height
= ¹/₂ * 14 * s/2
= 7s/2
Area of shaded region:
14s - 7s/2 = 84
Solving for s:
14s - 7s/2 = 84
28s - 7s = 168
21s = 168
s = 168/21
s = 8 inches

Answer:
1) The smallest is 1000, and the greatest is 9998.
2) The smallest is 1001 and the greatest is 9999.
Step-by-step explanation:
Four digit numbers:
The set of four digit numbers is: {1000, 1001, ...., 9998, 9999}
Even numbers:
End in 0, 2, 4, 6, 8
Odd numbers:
End in 1, 3, 5, 7, 9
1) the number is an even number
The smallest is 1000, and the greatest is 9998.
2)the number is an odd number
The smallest is 1001 and the greatest is 9999.
