Question 1173364
(a) 2y 
(b)-3x 
(c) mn  is {{{(m^1)(n^1)}}}, 1 Coefficient
(d) 1/2x^2 
(e) -we^2   -1 the coefficient
(f) -0.4gh^3 
2, -3, 1/2, -1 -0.4  as are coefficients as are 1(in c) and -1(in e), the rest(being letters) are variables
 
2)and 3) classification is according to how many terms it has separated by plus or minus signs 
2.{{{7x^2 + 3xy + 4y^2}}} is a trinomial 
a:monomial b:binomial c:trinomial d: term
3. classify each polynomial by the number of terms 
a) -2x  monomial  (A polynomial with just one term.)
b) 6y^2 +2y -1 trinomial 
c) a-1/2b   binomial 
d) 3u2 -uv +2v^2 trinomial 
e) ek^2 -1/2k  binomial 
f) m +0.2n- 0.3 + mn polynomial with 4 terms
4. the degree of {{{4u^1-5u^2+ 9}}} is 2 as that is the highest exponent
A: 1 b: 2 c:3 d:0
