The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.
The only option that fills in the values correctly is D
The answer choice for your problem would be b most likely
Answer:
The answer is A = 14 B = 4 14 - 4 = 10 I think.
Step-by-step explanation:
It's not a sum its a difference because this is a subtraction problem I think.
Ship fast equation for n packages:
2n+(1)x
where x the weight of the packages
Speedy delivery equation for the number of packages:
3n+(0.50)x
The same price happened when:
2n+(1)x = 3n+(0.50)x
x - 0.5x=3n - 2n
x = n/0.5
x = 2n
when the package weight is 2 pounds
