Option A is correct.
Step-by-step explanation:
We need to identify which statement is true in matrix addition.
In matrix addition we just add the corresponding elements.
In the options given only Option A is correct i.e, (n+4)-7 = 18
All other options have error in them.
In Option B there should be -12 instead of +12
In Option C there should be -11 instead of 11
In Option D we are not adding corresponding entries.
So, Option A is correct.

Answer:
1) 6^2 + 8^2 = x^2
36 + 64 = x^2
100 = x^2
x = 10 feet
2) 15^2 + 8^2 = x^2
225 + 64 = x^2
x ^ 2 = 289

*note that 1.45% = .0145*
Round that number to 3.05 and you have your answer
Answer:
A graphing calculator can do quadratic regression on the given points. It tells you the cost function is
.. c(x) = (1/2)x^2 +8x +10
Then c(12) = 178
The cost function predicts the total cost of producing 12 camera cases is $178.
