1 answer:
RoseWind [281]2 years ago
5 0

Answer:

  C.  I & III

Step-by-step explanation:

I simplifies to ...

  2(6x +15 -5x) +4 = 40

  12x +30 -10x +4 = 40

  2x +34 = 40

__

II simplifies to ...

  40 = 2(15 -x) +4

  40 = 30 -2x +4

  40 = -2x +34 . . . . . . not equivalent to I (sign of x-term is different)

__

III simplifies to ...

  12x +30 -10x +4 = 40

  2x +34 = 40 . . . . . . equivalent to I

___

I & III are equivalent

Please help!!! How many coefficients does this polynomial have in its complete form, including any missing terms?
frez [133]
-5x^3 + 2x^2 + 1

a coefficient is the number that is multiplied by the variable.For instance, the coefficient of 2x is 2....because 2 (the number) is multiplied by the variable x.

so in ur problem....there are 2 coefficients..-5 and 2.

** the number 1 is not a coefficient, it is a constant...a " loner " with no variables (letters) attached.

** and if u have just the letter...such as n, the coefficient to that is 1 but the one is just not written...it is actually 1n.

okay...I am gonna shut up now :)
