Answer:
A) x=3 or x=6
Step-by-step explanation:
Factor out the GCF : 2(x^2-9x+18)
Then, set to zero.
2(x^2-9x+18)=0
2(x-3)(x-6)=0
x=3 or x=6
Answer:
No
Step-by-step explanation:
Kilogram is the unit of weight. Kilogram is the measure of how much matter or the mass an object has in it. Kilogram is the bigger unit of measurement while gram and milligram are the smaller units to measure the weight of any object.
We know,
1 kilogram = 1000 gram x 1
So, 1000 gram is equal to 1 kilogram
That means, 39,000 gram is equal to 39 kilogram.
In the question it is asked whether 1000 pillows times 300 is equal to 39 kilogram sofa or not.
The answer is not correct, because we do not know the weight of the 1000 pillows.
And also, 1000 x 300 will give you 300,000 and not 39 kilogram or 39,000 grams.
Answer: 11 hours

(i think thats how you do it)
the period for one wave is 8π
Answer:
15 inches
Step-by-step explanation:
Call the original side length x
This makes the new length x+5
The perimeter is the sum of the length of the sides. So for the new shape this is 3(x+5)=60
This can be solved in the following way:
x+5=20
x=15
So the original side lengths were 15 inches.
