The sum of two monomials is not always a monomial and the product of two monomials is always a monomial.

Further explanation:

Explanation:

Consider the two monomials as 5y{\text{ and }}7y.

The sum of the two polynomials can be obtained as follows,

\begin{aligned}{\text{Sum}} &= 5y + 7y\\&= 12y\\\end{aligned}

The sum of the two monomials is monomial.

Consider the two monomials as 5y{\text{ and }}7x.

The sum of the two polynomials can be obtained as follows,

{\text{Sum}} = 5y + 7x

The sum of the two monomials is not monomial.

Consider the two monomials as 4y{\text{ and }}6x.

The product of the two polynomials can be obtained as follows,

\begin{aligned}{\text{Product}} &= 4y \times 6x\\&= 24xy\\\end{aligned}

The product of the two monomials is monomial.

The sum of two monomials is not always a monomial and the product of two monomials is always a monomial.

Sum of two monomials is not necessarily always a monomial.

For example:

Suppose we have two monomials as 2x and 5x.

Adding 2x+5x , we get 7x.

So if two monomials are both like terms then their sum will be a monomial.

Suppose we have two monomials as 3y and 4x

Now these are both monomials but unlike, so we cannot add them together and sum would be 3y + 4x , which is a binomial.

So if we have like terms then the sum is monomial but if we have unlike terms sum is binomial.

Product of monomials:

suppose we have 2x and 5y,

Product : 2x*5y = 10xy ( which is a monomial)

So yes product of two monomials is always a monomial.

What is the midpoint of a line segment with the endpoints (-4, -3) and (7, -5)
Katyanochek1 [597]
Midpoint Formula: (\frac{x+x}{2},\frac{y+y}{2})
Midpoint = (\frac {-4+7}{2},\frac {-3-5}{2})
Midpoint = (\frac {3}{2},\frac {-8}{2})
Midpoint = (\frac {3}{2}, -4)
So, the midpoint of the endpoints (-4,-3) and (7,-5) is (\frac {3}{2}, -4).

Let y- 2t+ 5 be a linear function representing the distance from home for an ant tminutes after starting out from a location nea
blondinia [14]

The 5 represents the starting distance from home. In other words, when t = 0, the value of y is y = 5. Replacing t with 0 leads to this y value. This is the y intercept. So at time 0 minutes, the ant is 5 units from home. Replace "units" with whatever units you happen to be using.
