Its 78/10 = 39/5
Hope it helps :)
16 times but the answer is 16.3(repeating)
30 is the answer. You do 10X 3 which is 30- 2 which is 28 and 28 to the nearest 10th is 30
When a quadratic equation ax^2+bx+c has a double root, the discriminant,
D=b^2-4ac=0
Here
a=2,
b=b,
c=18
and
D=b^2-4ac=b^2-4*2*18=0
solve for b
b^2-144=0
=> b= ± sqrt(144)= ± 12
So in order that the given equation has double roots, the possible values of b are ± 12.
