Julian fully simplifies this polynomial and then writes it in standard form. 4x2y2 – 2y4 – 8xy3 + 9x3y + 6y4 – 2xy3 – 3x4 + x2y2 if julian wrote the last term as –3x4, which must be the first term of his polynomial in standard form? a) 4y4 b) 6y4 c) –2xy3 d) –10xy3

4y^4

Step-by-step explanation:

Last term is -3x^4

This means x term is increasing and it ends at x^4

we arrange the terms in order

now we combine like terms

So first term is 4y^4

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
