Answer 3

To solve the expression, you need to perform the operations step by step. First, calculate the values inside the parentheses:

(7, 6 - 20) = (7, -14) (-3, 14 + 5, 24) = (-3, 38)

Now, multiply the two resulting vectors:

(7, -14) × (-3, 38)

To find the cross product of two 2D vectors (a, b) and (c, d), you can use the formula:

(a, b) × (c, d) = ad - bc

So in this case:

(7, -14) × (-3, 38) = (7 * 38) - (-14 * -3) = 266 - 42 = 224

Therefore, the result of the expression (7, 6 - 20) × (-3, 14 + 5, 24) is (0, 224).
