Answer:
It is 9x^3.
Step-by-step explanation:
36x^4 and 45x^3.
GCF of 36 and 45 = 9
GCF of x^4 and x^3 = x^3
GCF of 36x^4 and 45x^2 = 9x^3.
If it has rational coefients and is a polygon
if a+bi is a root then a-bi is also a root
the roots are -4 and 2+i
so then 2-i must also be a root
if the rots of a poly are r1 and r2 then the factors are
f(x)=(x-r1)(x-r2)
roots are -4 and 2+i and 2-i
f(x)=(x-(-4))(x-(2+i))(x-(2-i))
f(x)=(x+4)(x-2-i)(x-2+i)
expand
f(x)=x³-11x+20
(6+23)=29
(32-25)=7
(29)x(7)+(7x7)
203+49= 252
the answer is 252
Answer:
12
Step-by-step explanation:
a=3b
b=2c
c=4d
a*c/b*d = (3(2(4d)))*(4d)/(2(4d))*d
= 96d^2/8d^2
= 12
