Answer:
A
Step-by-step explanation:
P^T is transpote matrix. So the rows of matrix P you write like columns in P^T.
So we have first row: 2, 5, it will be firsl column
2nd row: 8,1 will be 2nd column.
It is matrix:
2 8
5 1
This is matrix a)
The commutative property of multiplication states that the order of multiplication of numbers does not matter.
Number Sentence:
2 * 3 = 3 * 2 = 6
0.05 rounded to the nearest whole number is 0.

<u><em>Answers:</em></u>
AD = 10 units
BD = 12 units
<u><em>Explanation:</em></u>
<u>1- getting AD:</u>
In an isosceles triangle, the two non-parallel sides are equal.
It is given that trapezium ABCD is isosceles which means that AD = BC
<u>We are given that:</u>
BC = 10 units
<u>Therefore:</u>
AD = BC = 10 units
<u>2- getting DB:</u>
In an isosceles trapezium, the diagonals are congruent
Since the given trapezium is isosceles and AC and BD are its diagonals, therefore:
AC = BD
<u>We are given that:</u>
AC = 12 units
<u>Therefore:</u>
BD = AC = 12 units
Hope this helps :)
