Joni should have multiplied by 1,000.
Step-by-step explanation:
Mass of the box = 67 decagrams
1 decagram = 1000 centigrams
So, 67 decagrams = 67 x 1000 centigrams
= 67000 centigrams
Joni should have multiplied by 1,000.

Answer:
2(3(8))+2(8)=64
Step-by-step explanation:
Here, w represents the width of the rectangle,
∵ length of the rectangle is 3 times the width of the rectangle,
So, length = 3w,
Since, the perimeter of a rectangle, P = 2(length + width)
= 2(w + 3w)
= 2w + 2(3w)
If P = 64 feet,
⇒ 2w +2(3w) = 64
⇒ 2w + 6w = 64
⇒ 8w = 64
⇒ w = 8
Verification :
P = 2(8) + 2((3(8)) = 16 + 48 = 64 feet
Hence, the first step that should be taken to verify that the width of the rectangle is 8 is 2(3(8))+2(8)=64
Note : a solution obtain from an equation is verified by substituting the value in the equation.

Answer:
The value of k is
The roots are -1 and
Step-by-step explanation:
In any quadratic equation the sum of its roots is and the product of its root is
In the equation
The sum is
The product is
∵ The sum of the roots is twice their product
∴
∴ ⇒Multiply both sides by k
1 + k = 6k + 4⇒ 1 - 4 = 6k - k
5k = -3 ⇒
Use the value of k in the equation:
⇒ Multiply equation by 5
⇒ Multiply equation by -1
⇒ use factorization to find roots
(3x - 1)(x + 1) = 0
3x -1 = 0⇒ 3x = 1⇒ x = 1/3
x + 1 = 0⇒ x = -1
The roots are 1/3 and -1
