The value of the expression (r + v)w will be (-45, 45, 14).
What is a vector?
The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
The vector r, v, and w are given below.
r = (9, 8, 3), v = (6, 7, -1), and w = (-3, 3, 7).
Then the value of the expression (r + v)w will be
(r + v) w = (9 + 6, 8 + 7, 3 – 1) × (-3, 3, 7)
(r + v) w = (15, 15, 2) × (-3, 3, 7)
(r + v) w = (-45, 45, 14)
