Answer:
x^2 + 10x - 9
Step-by-step explanation:
(1+2)3 = 1(x(x+10))
Answer:

Step-by-step explanation:
You have the following function:
(1)
In order to find the zeros of the function you equal to zero the equation (1), and then you solve for θ:

Then, there are infinite zeros for the function of the equation (1), because n has infinite positive integers values.
A. (m+n)(x)=
5x+4+6x-9=
11x-5
B. (mn)(x)=
(5x+4)(6x-9)=
30x^2+24x-45x-36=
30x^2-21x-36
C. basically sub n(x) for x in m(x)
m(n(x))=
5(6x-9)+4=
30x-45+4=
30x-41
Answer:
D) 20 in
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
Substituting what we know
980 pi = pi (7)^2 h
Divide each side by pi
980 pi /pi= pi 49 h/pi
980 = 49h
Divide each side by 49
980/49 = 49h/49
20 =h
