Answer:
option B
Step-by-step explanation:
We have:
3x^2+7x+3 and 5x^2+12x
where
a=3x^2+7x+3
b=5x^2+12x
a+b=3x^2+7x+3 +5x^2+12x
we sum each term:
3x^2+5x^2=8x^2
7x+12x=19x
3+0=3
so we have: a+b= 8x^2+19x+3
finally we have
8x^2+19x+3= option B

Answer:
(2) If 300 lunches were sold, then 120 chose tacos.
Step-by-step explanation:
We can evaluate each option and see if it makes it true.
For 1: If 200 lunches were served, 10 more students chose pizza over hotdogs.
We can find how many pizzas/hotdogs were given if 200 lunches were served by relating it to 100.
20% chose hotdog, which is . Multiply both the numerator and denominator by two: - so 40 students chose hotdogs.
Same logic for pizza: 30% chose pizza - so 60.
60 - 40 = 20, not 10, so 1 doesn't work.
2: If 300 lunches were sold, then 120 chose tacos.
Let's set up a proportion again. 40% of 100 is 40.
So 120 tacos were chosen - yes this works!
Hope this helped!
We are given the data here that there are 21 teams and that in the tournament, for each opponent, one team has to play with each other twice. The formula to follow here is T = n*(n-1)*z/2 where T is the total number of games played in total in the tournament, n is the number of teams who participated and z is the number of times they have to face in the eliminations. 2 is attributed to prevent the repetition of the count in the reverse of roles of the opponents. In this case, upon substitution, then T =21*20*2/2 = 420 games in total.
