Answer:
D
Step-by-step explanation:
Difference of cubes is as follows
x^3-y^3=(x-y)(x^2+y^2+xy)
*notice how the sign in the origonal equation is the same for the first part but then flipped for the second*****
8 can be rewritten as 2^3 so we have
x^3-2^3 which means that we can use the template from before
(x-2)(x^2+2^2+2x)
simplify the 2^2 into 4 and put the variables in front to get
(x-2)(x^2+2x+4)
This is the same as D
Answer:
a = 6
b = 3/4
Step-by-step explanation:
They both need to have the same slope.
The slope in the first equation is 6
That means that the second equation must have a = 6
They both need to have the same y intercept
The second equation has a y intercept of 3/4
Therefore b in the first equation, must be 3/4
The man's age is 57 years old.
To find this answer follow the steps below:
1. Subtract 29 from 200 to get 171.
2. Divide 171 by 3 to get 57.
To check this, use the equation 200 - (57 x 3) = 29.
1. 57 x 3 = 171. 200 - 171 = 29
2. 200 - 171 = 29. 29 = 29.
Thus meaning the man is 57 years old. I hope this helps!

377mi / 58mi/h=6.5h
377mi / 65mi/h = 5.8h
5.8h+6.5h= 12.3h
Hope this helps! :D
