Let m =26 what is the value of m - 11
answer: 6/52 (fraction)
we know that there is 26 black cards, therefore 2 black 7's we also know there is four 4's in the pack therefore we add the 2 + 4 = 6 and it has to be in a fraction so it becomes 6/52
discriminant is 36.
x²-4x-5 = 0 have two real solutions.
given equation is :
we have to find discriminant of above equation.
general quadratic equation is :
ax²+bx+c = 0
comparing general equation with quadratic equation,we get
a = 1 ,b= -4 and c = -5
the formula to find discriminant is :
d = b²-4ac
putting the values of a,b and c in formula to find discriminant,we get
d = (-4)²-4()
d = 16+20
d = 36 > 0
if an equation has discriminant real and perfect square ,there are exactly two real solutions.
hence, 36 is real and greater than zero,so give equation have two real solution.
divide 270 by 9 to get 30. since it's only 1/9, then your answer is 30!
