Answer:
12
Step-by-step explanation:
Essentially, 60 and the 5 us must be equal:
60=5u
Divide both sides by 5 to solve for u but keep the equation balanced.
12=u
Answer:
C angle 2
Step-by-step explanation:
Supplementary angles add to 180 degrees (or form a straight line)
The angles that form a straight line line angle 4 are either 2 or 3
1,2,4,8 (when divided by 32, the result is a whole number. This means that they can be multiplied to make 32)
Since mass is neither created nor destroyed, the missing items are;
<h3>What is nuclear reaction?</h3>
The term nuclear reaction has to do with the transformation of one nucleus to another. On this case, we are going to transform P u to c m.
Since mass is neither created nor destroyed, the missing items are;

Answer:
A = ![\dfrac{1}{16}\begin{bmatrix}a &-(a-4) \\ -(a+4) & a\end{bmatrix}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B16%7D%5Cbegin%7Bbmatrix%7Da%20%26-%28a-4%29%20%5C%5C%20-%28a%2B4%29%20%26%20a%5Cend%7Bbmatrix%7D)
Step-by-step explanation:
given,
Matrix =
A = ![\begin{bmatrix}a &a-4 \\ a+4 & a\end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7Da%20%26a-4%20%5C%5C%20a%2B4%20%26%20a%5Cend%7Bbmatrix%7D)
determinant of matrix
|A| = a×a - (a-4)(a+4)
|A| = a² - a² +16
|A| = 16
inverse of the matrix
to calculate inverse of two matrix interchange the term a₁₁ with a₂₂ and multiply the -ve with a₁₂ and a₂₁
the inverse is
A = ![\dfrac{1}{16}\begin{bmatrix}a &-(a-4) \\ -(a+4) & a\end{bmatrix}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B16%7D%5Cbegin%7Bbmatrix%7Da%20%26-%28a-4%29%20%5C%5C%20-%28a%2B4%29%20%26%20a%5Cend%7Bbmatrix%7D)
