Answer:
2. 
Step-by-step explanation:
Given:

We need to simplify the given expression;
Solution on simplifying the given expression we get;
First we will apply distributive property to remove the parenthesis we get;

Now Combining the like terms together we get;

Now adding and subtracting like terms we get;

Hence the equivalent expression for given expression is
.
Answer:
y + 7 = 45(x + 2).
Step-by-step explanation:
y - y1 = m(x - x1)
Here m = 45 and (x1, y1) = (-2, -7) so we have:
y - (-7) = 45(x - (-2))
y + 7 = 45(x + 2).
The equation of a circle is (x - a)² + (y - b)² = r², where the coordinates of the center(C) are C(a,b) and "r" the radius. Here, C(4,2) and if you need, r=3.

Answer:
I would say B
Step-by-step explanation:
when you are going down you tend to go faster because of gravity. So you would go down, up, down, up, and a little down. This would make B the answer because the speed is increasing when it goes down so that is the only answer that would make sense. Hope this helped! Have a good day! :)
