<span>–3(x + 3)^2 – 3 + 3x
</span>First, we expand the term to be squared:(x + 3)^2 = x^2 + 6x + 9So the expression becomes-3(x^2 + 6x + 9) - 3 + 3x-3x^2 - 18x - 27 - 3 + 3x-3x^2 - 15x - 30

This means that the object is miving at 6 miles per hour. Saying so it will take 6 hours to go 36 miles
Is this done or do you still need it answered?
Answer:
(c)
will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is ![=\frac{-1}{m}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-1%7D%7Bm%7D)
So the slope of the line which is perpendicular to y = 3x+2 will be ![=\frac{-1}{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-1%7D%7B3%7D)
Now (a) Line is given as
its slope is
so it will be not perpendicular
(b) Line is given as
its slope is
so it will be not perpendicular
(c) Line is given as
its slope is
so it will be perpendicular to the line y = 3x+2
(d) Line is given as
its slope is 3 so it will not perpendicular to the line y = 3x+2
