In this diagram, bac~edf. if the area of bac= 6 in.², what is the area of edf? PLZ HELP PLZ PLZ PLZ

NemiM [27]

Answer:

2.7 in²

Step-by-step explanation:

Area of ∆BAC : ∆Area of EDF = BC² : EF² (based on the area of similar triangles theorem)

Thus:

$6 in^2 : x in^2 = (3 in)^2 : (2 in)^2$

$\frac{6}{x} = \frac{3^2}{2^2}$

$\frac{6}{x} = 2.25$

$\frac{6}{x}*x = 2.25*x$

$6 = 2.25x$

$\frac{6}{2.25} = \frac{2.25x}{2.25}$

$2.67 = x$

Area of ∆EDF = 2.7 in²

What type of solutions does the quadratic equation, 8v2 + 8 = -11v, have?

Nat2105 [25]

Answer:

Complex roots

Step-by-step explanation:

Given

$8v^2 + 8 = -11v$

Required

The type of solution

Rewrite as:

$8v^2 +11v+ 8 = 0$

To determine the type of solution, we simply calculate the discriminant (D)

$D = b^2 - 4ac$

Where

$a = 8;\ \ \ b =11\ \ \ c = 8$

So, we have:

$D = 11^2 - 4 * 8 * 8$

$D = 121 - 256$

$D = -135$

The above value implies that:

$D$

When $D$ , the solution of the equation is: complex roots
