The expression 12xyz – 45 is a a. monomial. b. constant. c. binomial. d. trinomial.

Your answer is C. Binomial. :)

Terms are things in polynomials seperated by plus signs (a minus sign is adding a negative, so like a-b=a+(-b))

monomial has 1 term
bionomial has 2 terms
trionomial has 3 terms
constant is just like -34 or 23, no variable

so
12xyz-45
12xyz+(-45)
2 terms
bionomial
C is answer

Cbecause they are equal so that means it is the same on both sides? ! hope this

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )
