ANSWER
The correct answer is
.
<u>EXPLANATION</u>
We were given the matrix equation;
.
We must first simplify the Left Hand Side of the equation by adding corresponding entries.
.
That is;
.
Since the two matrices are equal, their corresponding entries are also equal. we equate corresponding entries and solve for m and n.
This implies that;

We got this equation from row one-column one entry of both matrices.

Also, the row three-column three entries of both matrices will give us the equation;


Hence the correct answer is
.
The correct option is option 2
Angle GEB is correspondent with the angle of 50°, and since the lines AB and CD are parallels, these angles must be congrunets, then
Answer: Second option 50°
Answer: Interval = [103,∞)
Explanation :
A medicine become ineffective if its temperature ever reaches 103 degrees Fahrenheit or more .
So, Interval becomes [103,∞)
i.e. semi-open or semi-closed interval as it includes 
So, we used closed brackets i.e. square brackets and
For '∞' we always use open brackets only.
