What is another name for this polynomial based on the number of terms it contains:
g(x)=-27x^3y^2
is it a trinomial?

Nope, that's a monomial. They're all stuck together since they're being multiplied, but if it were something like -27 - x^3 + y^2 where each term is separated by addition or subtraction, then it would be a trinomial.

The value of x is -0.5 ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to find a point which divides a line into two parts

- If point (x , y) divides a line whose endpoints are (x1 , y1) and (x2 , y2)

 at ratio m1 : m2 from (x1 , y1) to (x2 , y2), then

* Lets solve the problem

∵ Point A located at (0 , 4)

∵ Point B located at (-2 , -3)

∵ Point (x , y) located at 1/4 the distance from A to B

- That means the distance from A to point (x , y) is 1/4 the distance

  from point A to point B

∴ The distance from A to B is divided into four equal parts, where

   the distance between point A and point (x, y) is one and the

   distance between point (x, y) and point B is three

∴ Point (x , y) divide the line AB at ratio 1 : 3 ⇒ (1 + 3 = 4)

* Now lets find the x

∵ x-coordinate of point A is 0

∴ x1 = 0

∵ x-coordinate of point B is -2

∴ x2 = -2

∵ m1 = 1 , m2 = 3

- By using the rule above

∴

* The value of x is -0.5
