Answer: x = (sqrt(7) + 2)/3 and
x = ( – sqrt(7) + 2)/3
Explanation:
3x^2 - 4x - 1 = 0
Divide both sides by 3:
3x^2/3 - 4/3x - 1/3 = 0/3
x^2 - 4/3x - 1/3 = 0
x^2 - 4/3x = 1/3
x^2 - 4/3x + (2/3)^2 = 1/3 + (2/3)^2
(x - 2/3)^2 = 1/3 + 4/9
(x - 2/3)^2 = 7/9
Sqrt both sides:
x - 2/3 = sqrt (7/9)
x - 2/3 = |sqrt(7)/3|
Set x -2/3 = sqrt(7)/3
=> x = (sqrt(7) + 2)/3
Set x - 2/3 = - sqrt(7)/3
=> x = ( - sqrt(7) + 2)/3
Answer:
x=2
Step-by-step explanation:
Perimeter of a square = 4*(side of the square)
28 = 4*(3x+1)
28 = 12x + 4
28- 4 = 12x
24 = 12x
x =2
Answer:
Jim's box hold more t-shirts by 3 cubic feet
Step-by-step explanation:
Jim's box length = 2 feet
Jim's box breadth = 4 feet
Jim's box height = 6 feet
Volume of box =
Paul's box length = 3 feet
Paul's box breadth =5 feet
Paul's box height = 3 feet
Volume of box =
So,Jim's box hold more t shirts by (48-45 = 3 cubic feet )
So, Option C is true
Jim's box hold more t-shirts by 3 cubic feet
