2: They do not because the hypotenuse is larger and a^2 + b^2
3. The tiangle is acute because it has all angles smaller than 90*
12: The buillding is approximately 100 ft tall give or take. I am sorry If i am wrong on the last one
Since the multiplication between two matrices is not <em>commutative</em>, then
, regardless of the dimensions of

<h3>Is the product of two matrices commutative?</h3>
In linear algebra, we define the product of two matrices as follows:
, where
,
and
(1)
Where each element of the matrix is equal to the following dot product:
, where 1 ≤ i ≤ m and 1 ≤ j ≤ n. (2)
Because of (2), we can infer that the product of two matrices, no matter what dimensions each matrix may have, is not <em>commutative</em> because of the nature and characteristics of the definition itself, which implies operating on a row of the <em>former</em> matrix and a column of the <em>latter</em> matrix.
Such <em>"arbitrariness"</em> means that <em>resulting</em> value for
will be different if the order between
and
is changed and even the dimensions of
may be different. Therefore, the proposition is false.

Answer:
what do you need to to know 1) what kind of function its or 2) whats the answer of y and/or x
Do 1. It’s a hypotenuse so do 1 and find x
