This is the concept of quadratic equations, solving the equation 2x^2-12x+20=0 using the formula we get:
x=[-b+/-sqrt(b^2-4ac)]/(2a)
from our equation, a=2,b=-12 and c=20
x=[-(-12+/-sqrt((-12)^2-4*2*20)]/(2*2)
x=[12+/-sqrt(144-160]/4
x=[12+/-sqrt(-16)]/4
x=[12+/-4i]/4
x=[3+\-i]
the answer is A] 3+/-i
I think it’s will be 1 but I not sure it’s common 0 give 1
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
Well, Anita, I am glad to help out... Don't forget to rate my answer:)
Multiply both the numerator and the denominator by the same number and you'll get an equivalent fraction. For example, 3/5 times 2/2 equals 6/10, which is an equivalent fraction to 3/5. Multiply both by 8, and you have 24/40, which is also equivalent to 3/5. I hope this helped you tremendously! <span />
