19. 2x²+5√3 x+6 = 0​

Mathematics
1 answer:
Mama L [17]2 years ago
7 0

Answer:

Step-by-step explanation:

2x²+5√3 x+6 = 0​

Comparing this with quadratic equation ax^2+bx+c=0

So a=2,b=5√3,c=6

Discriminant D=b^2-4ac

D=(5√3)^2-4.2.6

= 75-48

=27.

27 >0

Hence the roots are real roots

X=(-b+√D)/2a, Y=(-b-√D)/2a

X=(-5√3+√27)/2×2, Y=(-5√3-√27)/2×2

X=(-5√3+3√3)/4,. Y=(-5√3-3√3) /4

X=-2√3/4,. Y=-8√3/4

X=-√3/2, Y =-2√3

So roots are X=-√3/2,Y=-2√3

What is 12 times 2 times 5 plus 2​
Vsevolod [243]

Answer:

122

Step-by-step explanation:

12 times 2 times 5 plus 2 gets rewritten as

(12)(2)(5) + 2

Follow PEMDAS and do multiplication first.  From left to right...

 24(5) + 2                      {   (12)(2) = 24   }

   120 + 2                        {  (24)(5) = 120   }

  122                               {   120 + 2 = 122   }

So you would do,
18 gallons of water divided by 0.5 gallons of water 
if you did that correctly you should have gotten... 36 jugs
