A tape measure will give LxWxH of the box giving you volume
Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
The answer would be, A) +$2 because he spend $12 but earned $14 so when you subtract 14 and 12 you get $2, which would be his profit
If the item is 30% off, the new price is 0.7p because we want to know how much 70% of the original price was.
Answer:
Equation is 
and when y=2 and z=4, x will be 4.
Step-by-step explanation:
Given:
x varies jointly with y and z.
It also means x is directly proportional to y and z.
From above values we can compute the equation as.
Hence the Equation is
Now y=2 and z=4 we get.
Hence when y=2 and z=4, x will be 4.
