Question

if ( c=(9,-9) ) and ( d=(7,5) ), find the sum ( c + d ).
( c + d=langlesquare,square
angle )

Explanation:

Step1: Add the x - components

The x - component of \(c\) is \(9\) and the x - component of \(d\) is \(7\). So, \(9 + 7\).
$$9+7 = 16$$

Step2: Add the y - components

The y - component of \(c\) is \(-9\) and the y - component of \(d\) is \(5\). So, \(-9+5\).
$$-9 + 5=-4$$

Answer:

\(\langle16,-4
angle\)
