Why are the following expressions not monomials?
3cdx
x+2w
3/h
ab-1

which expressions are monomials?

– 4 + 6

b + 2b + 2

(x – 2x)2

rs/t

36x2yz3

ax

x^1/3

Step-by-step explanation/

These expression are polynomials.

polynomials- A polynomial is an expression that consist with variables and coefficients that involves only subtraction,addition,division,or multiplication.

Monomial is a type of polynomial. Monomial consist of one term.

example of a monomial is down below.....

Why are the following expressions not monomial?

3/h is not a monomial because a variable is being divided if you put into fraction form the variable is in the denominator. which makes it not a monomial.

ab-1 has a negative exponent so this is incorrect

x+2w this more than one variable so its not one term. therefore its not a monomial.

3cdx has 3 variable being multiplied by each other so it would look like this

3*c*d*x this is not a monomial because its more than one term.

Which expressions are monomial?

b+2b+2 has 3 terms so this is a trinomial not a monomial.

(x-2x)2 we need to simplify to see if this is a monomial

2x*2=4x

x*2=2x

2x-4x= -2x

-2x is a monomial

-4+6 is not a monomial or a polynomial because it doesnt have a variable.

rs/t is not a polynomial becuase a variable is being divided and cannot be simplifed

36x2yz3  is a monomial since its just one term.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
