Answer:
||| First row: 11 -20 23 ||| Second row: -21 5 -24 ||| Third row: 6 9 -14 |||
Step-by-step explanation:
I wish I could explain it better, but all I did was plug it into matrix A on:

I pressed "find" without changing any of the settings, and scrolled down until I saw what was in the attached screenshot.
Each of the rows correspond to the first, second, and third answers, as you can see.
I hope this helps!
It is Negative 71. Work it out
Answer:
11=0
or
-11=0
keep in mind that you get these answers by completely simplifying the equation, but they are both false
Step-by-step explanation:
step 1: simplify both sides
2-16.5 simplifies to -14.5
4-7.5 simplifies to -3.5
so you get -3.5 = -14.5
step 2: add one side to the other to get a zero on one side
add 3.5 on both sides to get 0=-11
or
add 14.5 on both sides to get 11=0
step 3: evaluate the statement
since both -11 and 11 are not equal to 0, this statement is false
The Pythagorean Theorem states that "When a triangle has a right angle of (90°), the square of its hypothenuse is equal to the sum of the squares of the other two sides."
The hypothenuse is the longest side of the triangle.
For example: A triangle has 3 sides. Side A, Side B, and Side C (hypothenuse).
Side A = 3; Side B = 4; Side C = 5; To check if the theorem is true, we must square all sides.
Side A = 3² = 9; Side B = 4² = 16; Side C = 5² = 25
Pythagorean theorem: The square of the hypothenuse is equal to the sum of the squares of two sides.
<span>Side A² + Side B² = Side C² ==> 9 + 16 = 25 ==> 25 = 25</span>
Is there a picture that I can see of the question
