Answer:

a^2 + b^2 = c^2

2.7^2 + 2.7^2 = x^2

7.29 + 7.29 = x^2

14.58 = x^2

3.8 = x

Answer is B

kondaur [170]
L=16
W=21

Set up a systems of equations: 
x=length 
y=width 

xy=336
x+5=y

Use substitution to solve: 
x(x+5)=336
x^2+5x=336 

Solve using factoring: 
x^2+5x-336=0
(x-16)(x+21)=0
x=16 and x= -21 
Since length can't be negative, l=16 

To find width, plug length into the first equation: 
(16)y=336
y=21 

So...
L=16
<span>W=21</span>

compute the value of the discriminant and give the number of real solutions of the quadratic equation. -2x²+3x+5=0
SCORPION-xisa [38]

Given a quadratic equation in standard form

y=ax^2+bx+c

The discriminant D

D=b^2-4ac

tells the types of roots the equation has.

In this case, we have

\begin{gathered} -2x^2+3x+5=0 \\ a=-2 \\ b=3 \\ c=5 \end{gathered}

Then, the discriminant of this quadratic equation will be

\begin{gathered} D=b^2-4ac \\ D=(3)^2-4(-2)(5) \\ D=9+40 \\ \mathbf{D=49} \end{gathered}

Finally, the value of discriminat is 49 and as he discriminant is greater than zero then this quadratic equation has 2 different real solutions.
