(D)
Answer:
Verified
Step-by-step explanation:
Let the 2x2 matrix A be in the form of:
Where det(A) = ad - bc # 0 so A is nonsingular:
Then the transposed version of A is
Then the inverted version of transposed A is
The inverted version of A is:
The transposed version of inverted A is:
We can see that
So this theorem is true for 2 x 2 matrices
7 x times 14.6 x
<em>Multiply 7 and 14.6 and add exponents</em>
Final Answer 102.2 and

Answer:
x³ - 3x² - 18x
Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = xᵃ⁺ᵇ
Now, for the given:
To solve thus question, we will simply multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final answer.
This can be done as follows:
(x + 3)(x² - 6x)
x(x²) + x(-6x) + 3(x²) + 3(-6x)
x³ - 6x² + 3x² - 18x
x³ - 3x² - 18x
Hope this helps :)
