Answer: 3.2x = 12.8
Step-by-step explanation: Lets have x equal each box that weighs 3.2 pounds.
The expression: 3.2x = 12.8 represents that each box, x of candies will weigh 3.2 pounds and the total weight of the candies will equal 12.8 pounds of candy.
Additional: There are 4 boxes of candy, 12.8 divided by 3.2 = 4

Step-by-step explanation:
Answer:
B. The vectors v and w are orthogonal because their dot product is <u> 0 </u>
Step-by-step explanation:
Given that :
v= - i - j
w= - i + j
Therefore;
vw = ( - i - j ) ( - i + j )
Taking each set of integer of the vector into consideration:
vw = ( -1 × - 1) ( -1 × 1)
vw = 1 - 1
vw = 0
Hence, we can conclude that :
The vectors v and w are orthogonal because their dot product is <u> 0 </u>
