Rearranging what you have you get

\frac{2}{3}x^2+\frac{2}{3}x-\frac{43}{3}=0, thus

a=\frac{2}{3}, b=\frac{2}{3}, c=\frac{43}{3}

The first step is to write this equation into general form. The general form of an equation is:

ax^2 + bx + c = 0

To make this equation to general form, you have to simplify the equation first.

2/3(x-4) (x+5) = 1

2/3 (x^2 + 5x – 4x – 20) = 1

2/3(x^2 + x -20) = 1

2/3x^2 + 2/3x – 40/3 = 1

2/3x^2 + 2/3x – 40/3 – 1 = 0

2/3x^2 +2/3x – 43/3 = 0

Therefore, a = 2/3 ; b = 2/3 ; c = -43/3

You can use the similarity approach of these two triangles CBD and CAE

as a result:
\frac{BD}{AE} = \frac{10}{2x} = \frac{CD}{CE} = \frac{3x}{?}

so:
? = 6x^2 / 10 = 0.6 x^2

and the fact of:

"The segment connecting the midpoints of two sides of a triangle is parallel to the third side and equals its half length"

so:BD = 0.5 AE        10 = 0.5 * 2x        >>> x= 10


Back to:
? =0.6 x^2 = 0.6 * 10^2 = 0.6 * 100 = 60



A

Hope that helps

Find the product 0 . 67 × 0 .3
quester [9]
0.067 =67/100
0.3 =3/10
0.67 * 0.3 = 67/100 *3/10
(67*3) / (100*10)
=201/1000
=0.201
