They tell you that the first term is 7 so that cancels out the last answer choice immediately. Then they tell you that each term is multiplied by 4 so when you multiply 7x4 you get 28. This cancels out the second to last answer. Then keep multiplying by 4. 28x4 is 112. 112x4 is 448.
Therefore, the obvious answer is the first choice!

The information that shows 
by SSS
By SSS implies that, the three sides of both triangles are congruent
Already, we have:
The third side of 
is 
The third side of 
is 
So, for both to be congruent by SSS, the third sides must be congruent
i.e.
Step-by-step explanation:
You can solve systems of equations using either substitution or elimination. For these problems, I recommend elimination. I'll do the first one as an example.
-3x + 16y = 9
-4x + 8y = 12
Multiply the second equation by -2.
8x − 16y = -24
Add to the first equation (notice the y's cancel out).
(-3x + 16y) + (8x − 16y) = 9 − 24
5x = -15
Solve for x.
x = -3
Now you can plug this into either equation to find y.
-3(-3) + 16y = 9
9 + 16y = 9
y = 0
The solution is (-3, 0).
