The two numbers multiply to 64 and add up to negative 16 are -8, -8.
What is Algebraic expression ?
Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.
Let us assume first number be = x
and, let the second number be = y
then,
multiplication of two number will be :
xy = 64...(1)
addition of two numbers will be -16 that is :
x + y = -16..(2)
we have :
(x+y)² - (x-y)² = 4xy
(x-y)² = (x+y)² - 4xy
(x-y)² = (-16)² - 4 x 64
(x-y)² = 256 - 256
(x-y)² = 0
(x-y) = 0
x = y
Now, from equation (2) we have ":
x + y = -16
x + x = -16
2x = -16
x = y= -8
Therefore, the two numbers multiply to 64 and add up to negative 16 are -8, -8.

Hello!
Answer:
Step-by-step explanation:
→ We want to find the next term of this sequence:
→ The sequence (-1, -3, -5, -7, -9, ...) is an arithmetic sequence because the difference between any two consecutive terms is constant.
→ The common difference is -2.
→ So the next term of this sequence is equal to:
Conclusion:
The next term of the sequence (-1, -3, -5, -7, -9, ...) is -11.
First lets solve for the volume of the swimming pool. The formula for volume of a rectangular prism is:
V=l*w*h
How lets plug in our known values...
V=50*25*3=3750m³
1liter=0.001m³
1000liters=1m³
1000liters x liters
________=________
1 m³ 3750m³
Cross Multiply
1x=3,750,000 liters
Answer=3,750,000 liters
Answer:
hours will it take to fill 4 aquarium
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity 1, such as 3 feet per second or 6 miles per hour, they are called unit rate
As per the statement: Terrence was filling the new fish aquariums where he works. He was able to fill aquariums in
hours.
Substitute the given values we get;
Simplify:
Now, to find the number of hours will it take to fill 4 aquarium.
or
therefore, it will take to fill aquarium is, hours
