The result of a multiplication operation is called a product.
So, to prove product of two negative integers is not negative
Taking the example of (-1) ·(-1).
Now since multiplying two negative numbers always gives positive result.
Thus, (-1) ·(-1) = +1
which is not negative.
Thus, the product of two negative integers is not negative because multiplying two negative numbers always gives positive result.

Complete the net worth statement by determining the total assets and total liabilities. What is the net worth?
A) $200
B) $2,000
C) $10,700
D) $12,700
Answer:
B
Step-by-step explanation:
1. Add all of the assets($12,700) and all of the liabilities($10,700).
2. Subtract the liabilities from the assets.
The total net worth of the given assets and liabilities is $2000.
What is the net worth?The net worth is the difference between the total assets and the total liabilities.

Step-by-step explanation: Set up the equation so that their distances will be equal at some time, x.
Distance = speed × time
3x + 15 = 4x . Subtract 3x from both sides
15 = 4x-3x
15 = x The time is 15 seconds.
At that point their distances will be equal at 60 feet.
3(15) + 15 = 60
4(15) = 60

Arrange the following measurements in order from smallest to largest
4.1 liters, 0.7 liters and 2,000 millimeters
Answer:
first we change 2000mm into litres and I think 1000 mm is equals to 1 L then you look at the first digit and in the first number we have for as the first digit the second number 0 the third number two so in this case 0.7 l is the smallest then 2000mm then 4.1 letters
The measurements in order from smallest to largest is,
0.7 liters, 2,000 millimeters, 4.1 liters
Here,
Given measurements are, 4.1 liters, 0.7 liters and 2,000 millimeters
We have to arrange in order from smallest to largest.
What is Measurements?
The process of associating numbers with physical quantities and phenomena is called Measurements.
Now,
1 liters = 1,000 millimeters
Hence, 2,000 millimeters = 2,000/1,000 = 2 liters
So,
The measurements in order from smallest to largest is,
⇒ 0.7 liters, 2 liters, 4.1 liters
⇒ 0.7 liters, 2,000 millimeters, 4.1 liters
