I’m pretty sure the answer would be B
The solution of the equation x2+7x is 0, -7 using the quadratic formula.
Step-by-step explanation:
x2 + 7x = 0
-b ± √
b2 - 4(ac)/ 2a
substitution,
a = 1, b = 7, c = 0
= -7 ± √(7)2 - 4(1 x 0) / 2 x 1
= - 7
± 7 / 2
x = 0 , -7

Answer:
Michael bought 18 tacos and 9 burritos.
Step-by-step explanation:
Since at a particular fast food restaurant, tacos cost $ 1.29 and burritos cost $ 2.19, and Michael spent a total of $ 42.93 at the restaurant to buy food for a party, if he purchased half as many burritos as tacos, to determine how many tacos did he buy, the following calculation must be performed:
1.29 x 20 + 2.19 x 10 = 47.7
1.29 x 16 + 2.19 x 8 = 38.16
1.29 x 18 + 2.19 x 9 = 42.93
So Michael bought 18 tacos and 9 burritos.
It would stay the same. Hope this helps :)
