Please, I need help I'm way behind.
gregori [183]

Answer:

\frac{18√2}{√3}

Step-by-step explanation:

  1. The lengths of the sides of a 30-60-90 triangle are in the ratio 1:2:√3.
  2. The lengths of the sides of a 45-45-90 triangle are in the ratio 1 : 1 : √2
  3. We can get the length of the longest side of the bottom triangle is 9×2÷√3 = \frac{18}{√3}
  4. And based on the theory shown on the 2nd step, we can get x (the length of the longest side of the upper triangle) is \frac{18}{√3}x√2

Marley was asked to solve x2 - 4x + 9 = 0 using the Quadratic Formula. She found the discriminant first and decided she did not
saveliy_v [14]

We have been given Marley was asked to solve x^2-4x+9 = 0 using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.

We are asked to determine whether Marley is correct or not.

We know when an equation is in form ax^2+bx+c=0, we can use discriminant to check for the real solutions of equation.

D=b^2-4(a)(c)

If D>0, then the equation will have two real solutions.

If D=0, then the equation will have one real solution.

If D, then the equation will have no real solutions.

Let us find discriminant.

a=1,b=-4\text { and }c=9

D=(-4)^2-4(1)(9)

D=16-36

D=-20

Since -20, therefore, the equation will have no real solutions, so Marley is correct.
