Answer:
x-3
Step-by-step explanation:
x representing the amount of money on the gift card
41.
Take 10 * 8.2 (Easier this way)
You get 82.
Take 82 *1/2 (or divide by 2)
You get 41.
Using the distributive law:-
this = sqrt 14 sqrt 12 + sqrt 14 sqrt 7 - sqrt 3 sqrt 12 - sqrt 3 sqrt 7
= sqrt1 68 + sqrt 91 - sqrt 36 - sqrt 21
= sqrt 168 + sqrt 91 - sqrt21 - 6
