Answer:
<6
Step-by-step explanation:
Corresponding angles have the same matching corner.
<6 has the same matching corner as <2. <6 and <2 are congruent.
Therefore, it can be concluded that <6 corresponds to <2.
5.1x10^6 is the greatest because when u multiply it, it is 5 million
Answer:
bottom side (a) = 3.36 ft
lateral side (b) = 4.68 ft
Step-by-step explanation:
We have to maximize the area of the window, subject to a constraint in the perimeter of the window.
If we defined a as the bottom side, and b as the lateral side, we have the area defined as:

The restriction is that the perimeter have to be 12 ft at most:

We can express b in function of a as:

Then, the area become:

To maximize the area, we derive and equal to zero:

Then, b is:

My answer is C
because
x-12=-3
x=-3+12
x=9
I wanna say the 1st or the last one
