If P = ∣∣∣5321∣∣∣ | 5 3 2 1 | and Q = ∣∣∣4235∣∣∣ | 4 2 3 5 | , find 2P + Q

If P = $\left|\begin{array}{cc}5& 3\\ 2& 1\end{array}\right|$ and Q = $\left|\begin{array}{cc}4& 2\\ 3& 5\end{array}\right|$, find 2P + Q

Answer Details

Given that P = |5321| and Q = |4235|, we need to find 2P + Q. First, we need to evaluate P and Q. The vertical bars indicate the absolute value of the number, which means the distance of the number from zero on the number line. Therefore, we have: P = |5321| = 5321 Q = |4235| = 4235 Now, we can substitute these values in 2P + Q and simplify: 2P + Q = 2(5321) + 4235 = 10642 + 4235 = 14877 Therefore, the value of 2P + Q is 14877. Hence, the answer is option B, i.e., |14877|.
