Answer:
Discriminant = 49, two real solutions
Step-by-step explanation:
Discriminant = b² - 4ac = (5)² - 4(3)(-2) = 25 + 24 = 49
Since 49>0, then the quadratic equation has two real solutions.

LH=legnth times height
HW=height times width
LW=legnth times width
surface area=2(LH+LW+WH)
A surface area is 2(5*6+5*7+6*7)=214
b surface area is double everybody si
2(10*12+10*14+12*14)=856
214 times 2=428
he is wrong
how many times as great?
856/214=4
answer is 4 times

15% of 300 = 45 ( foot )
300 x 3/5 = 180 ( bus )
therefore, students arrive by car = 300-180-45= 75
