3. The distance a person walks, d, in kilometers, is a function of time, t, in minutes, since the walk begins. Select all true statements about the input variable of this function.
Select all that apply:
A. Distance is the input
B. Time of day is the input
C. Time since the person starts walking is the input
D. t represents the input
E. d represents the input
F. the input is not measured in any particular unit
G. for each input, there are sometimes two outputs
H. the input is measured in hours

if x = 1, then the answer is 3.5

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
