Answer:
c = 12.5903 as it is more accurate
Step-by-step explanation:
tan65 = 27/d , value of tan65 is 2.1445
2.1445 = 27/d
d = 27/2.1445
d = 12.5903
so answer would be c as it is more accurate than others.

Answer:
2(multiplicity 2)
Step-by-step explanation:
2 is repeated twice in the function.
Answer:
x=-1,-3,2i and -2i
Step-by-step explanation:
By plugging in x=-1, f(x)=0 and x=-3,f(x)=0
That means x+1 and x+3 are roots of the fourth degree polynomial.
(x+1)(x+3)=x²+4x+3
Divide the polynomial by x²+4x+3 and that gives x²+4.
We now find the zeros of the factors
(x²+4x+3)(x²+4)=0
x=-1,-3,2i and -2i
