9-8x^2+2x^4 is this a trinomial​
Svetradugi [14.3K]

Yes. A monomial is a term composed by a coefficient and powers of variables multiplied with each other, for example

3xy^3z^2

is a monomial.

In your case, the monomials are

9,\quad 8x^2,\quad 2x^4

As the name suggests, a trinomial is the sum of three monomials, which is exactly your case.

5+ 1/5x=5 what is x
Alenkasestr [34]

Answer:

x = 0

Step-by-step explanation:

Solve for x:

x/5 + 5 = 5

Put each term in x/5 + 5 over the common denominator 5: x/5 + 5 = x/5 + 25/5:

x/5 + 25/5 = 5

x/5 + 25/5 = (x + 25)/5:

(x + 25)/5 = 5

Multiply both sides of (x + 25)/5 = 5 by 5:

(5 (x + 25))/5 = 5×5

(5 (x + 25))/5 = 5/5×(x + 25) = x + 25:

x + 25 = 5×5

5×5 = 25:

x + 25 = 25

Subtract 25 from both sides:

x + (25 - 25) = 25 - 25

25 - 25 = 0:

x = 25 - 25

25 - 25 = 0:

Answer:  x = 0
