ANSWER
B. The two middle coefficients add to the correct number but do not multiply to the correct number.
EXPLANATION
The given quadratic trinomial that Tina tries to factor is
Comparing to
we have a=10, b=-13 and c=-3
ac=-3×10=-30
We split the middle term so that their sum is -13.
Tina use
-10,-3
to get
-10x-3x
The sum is -13x alright but the product is not -30.
B is correct.
Answer:
B I think
Step-by-step explanation:
Answer: (13 + y) / 5
Step-by-step explanation:
Since Grandma Gertrude gave 13 pieces of jewelry and Grandma Fien gave y pieces of jewelry to the Carlson sisters, the total jewellery given to the sisters will be:
= 13 + y
Since there are 5 Carlson sisters, the number of pieces of jewelry that each sister receive will be:
= Total jewelries / Number of sisters
= (13 + y) / 5

Step-by-step explanation:
The attached graph shows the cumulative costs of owning an AIBO.
$2899.99 (about $2900) includes fixed cost of Toy Ball, Charging Station
Several years of AI cloud service is a variable cost because this is changing and it helps the robot dog "learn". It is going to cost after some time. But how long?
Looking at the cost of an AIBO, we see that until 3 years, the cost line is veyr close to 3000 dollars, we can say 2899.99 dollars. After 3 years, the cost rises with a slope. Now, this is the cost of AI cloud service being IMPOSED after first 3 years of being "free".
Thus,
We can say that service is free for first 3 years. We know by looking at the graph shown.
