"The definition of good mathematical problem is the mathematics it generates rather than the problem itself"
Andrew Willes
ANSWER:People interpret things differently there have been math problems that were told to be unsolved until someone viewed it differently and solved it. If you never try it, you will never solve it. Some problems seem simple but you try them for a year, ten years, a hundred years and it turns out they are extremely hard to solve. Simple but challanging math problems. The Good Math problems are those that look simple but are hard to solve. The problem itself looks simple But the math it generates is hard and complex to solve.
It is saying that to have a good mathematical problem depends on what that problem is (generates)
Some mathematical problems will be easier or harder than others.
But It is saying that the definition of a good problem is because it's mathematical not what the quesiton is.

if an object has a density of 6.g/mL and you put it into water, will it sink or float?
Step-by-step explanation:
If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.
Maurice and his father are building a dog house. They are using long pieces of wood and cutting them into smaller pieces. They have a piece of wood that is 3.6 feet long and are cutting it into pieces that are each 0.75 feet. How many smaller pieces will they be able to make?
Answer:
4.8 smaller pieces
Step-by-step explanation:
Total length of wood = 3.6 feet
Length of each piece = 0.75 feet
How many smaller pieces will they be able to make?
Number of smaller pieces of wood = Total length of wood / Length of each piece
= 3.6 feet / 0.75 feet
= 4.8 smaller pieces
Number of smaller pieces of wood = 4.8

5. What is the perimeter of a rectangle with a length of 9x - 4 and a width of 5x+2?
Answer:
14x-2
Step-by-step explanation:
In order to find the perimeter we need to add the length and width together. So adding 5x and 9x gives us 14x. -4+2=-2
The perimeter of a rectangle with a length of 9x - 4 and a width of 5x+2 is, 28x-4
What is the perimeter?Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.
Perimeter = Sum of length of the all the sides
Given that,
length of rectangle = 9x - 4
width of rectangle = 5x+2
As we know,
Perimeter = Sum of length of the all the sides
Perimeter = (9x - 4) + (5x+2) + (5x+2) + (9x - 4)
Perimeter = 28x-4
Hence, The perimeter is 28x-4

Anna made and sold x ceramic vases one week. Her profit, P, in dollars is calculated using the formula P = R - C . Where R represents her revenue and C represents her costs. If R = 25x - 0.5x ^ 2 C = 100 + 5x which expression represents her profit in dollars?
Answer:
-0.5x² + 20x + 100
Step-by-step explanation:
Given:
R = 25x - 0.5x²
C = 100 + 5x
P = R - C
Where,
P = profits
R = Revenue
C = Cost
which expression represents her profit in dollars?
P = R - C
R = 25x - 0.5x²
C = 100 + 5x
= 25x - 0.5x² -(-100 + 5x )
= 25x - 0.5x² + 100 - 5x
= -0.5x² + 20x + 100
The expression which represents her profit in dollars is -0.5x² + 20x + 100
