Answer 3

To evaluate the expression (p-4q)(2p+q) when p=3 and q=8, you simply substitute the values of p and q into the expression and perform the arithmetic operations.

Let's calculate it step-by-step:

Step 1: Substitute the values of p and q into the expression. (p-4q)(2p+q) = (3 - 4 * 8)(2 * 3 + 8)

Step 2: Perform the arithmetic operations inside the parentheses. (3 - 32)(6 + 8)

Step 3: Perform the remaining operations. (-29)(14)

Step 4: Finally, calculate the result. -29 * 14 = -406

So, when p=3 and q=8, the expression (p-4q)(2p+q) evaluates to -406.
