Answer:

Hey there! Your answer would be:  3x^2+4=x

The quadratic formula is (-b±√(b²-4ac))/(2a), and helps us find roots to a quadratic equation.

All quadratic equations can be written in the ax^2+bx+c form, and a, b, and c, are numbers we need for the quadratic equation.

Our given quadratic equation is 1±√(-1)²-4(3)(4)/2(3)

We can see that b is -1, as -b is positive 1.

That gives us  ax^2+-1x+c, which can be simplified to ax^2-x+c.

We can see that a is 3, because 2a=6, so a has to be 3.

That gives us 3x^2-x+c

Finally, we see that 4 is equal to b, clearly shown in the numerator of this fraction.

Which gives us a final answer of 3x^2-x+4, or 3x^2+4=x

What is the simple interest earned on $3,672 at 4.5% for three years?
olasank [31]

Answer: interest at the end of 3 years is $495.72

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

T = 3 years

P = $3,672

R = 4.5%

Therefore

I = (3672 × 4.5 × 3)/100

I = 49572/100

I = 495.72

A. x∧2+(x+20∧2=150∧2  is correct.

because you need to plug the numbers into the pathagoreum theorum which is 
a∧2+b∧2=c∧2

150 is our c because it is the side right accross from the right angle.

which number is a and which number is b does not matter.

x is the distance north so we can assign that to a and the distace east is north plus 20 so we can assign b to x+20.
