Answer:
b
Step-by-step explanation:
The formula to finding a discriminant would be b^2-4ac, the b value of this trinomial being -5, the a value being 2, the c value being 3. Then, you plug the values in the equation and solve: (-5)^2-4(2)(3)
This would simplify to 1, meaning there are two solutions since the discriminant value is positive. If it is 0, there is one solution, if it is negative, then there are no real solutions.
0.3 or 30% is the same as 3/10
Answer:
John is 9 and Olivia is 12
Step-by-step explanation:
12+18= 20
36+ (9x8)= 108
Subtract 18 from 72 to get Michelle's current age.
72 - 18 = 54
