Answer:
AC = 10
Step-by-step explanation:
Formula
(x + 1) + (x + 3) + 2x = 40 Remove the brackets
Solution
x + 1 + x + 3 + 2x = 40 Collect like terms
4x + 4 = 40 Subtract 4 from both sides
4x +4 -4 = 40 - 4 Combine
4x = 36 Divide both sides by 4
4x/4 = 36/4
x = 9
AC = x + 1
AC = 9 + 1
AC = 10
If the value of |A| is 48 the possible values for x in the matrix is 4 or -2.
<h3>How to use determinant to find a value in a matrix?</h3>
The determinant of the matrix A is as follows:
|A| = 48
Therefore,
48 = (3x × 2x) - (4x × 3)
48 = 6x² - 12x
6x² - 12x - 48 = 0
3x² - 6x - 24 = 0
x² - 2x - 8 = 0
x² + 2x - 4x - 8 = 0
x(x + 2 -4(x + 2) = 0
(x - 4)(x +2) = 0
Therefore,
x = 4 or -2
