Solve for x. A) 3.0 B) 3.25 C) 3.5 D) 3.75
1 answer:
Answer: D) 3.75
Step-by-step explanation:
According to the Insersecting chords theorem, when you multiply the lengths of the segments of one of the chords in a circle, the product obtained is equal to the product of the segments of the other chord.
Based on this, you can find the value of "x" with:
Solve for "x" (Applying the Division property of equality, you can divide both sides of the equation by 4). Then:
This value matches with the option D.

Not possible.
Step-by-step explanation:
Addition of Matrix A and Matrix B is possible only if the order of matrix A is same as the order of matrix B.
Order of a matrix with rows and
columns is
.
Here, matrix A is
Matrix B is .
Multiplying a matrix by a constant doesn't change its order.
So, order of matrix A is as it has 3 rows and 2 columns.
The order of matrix 3B is as it has 2 rows and 3 columns.
Therefore, addition is not possible as the order is different.
