Answer:

8.5 units ^2

Step-by-step explanation:

Area of whole rectangle 3 x 6 = 18 units^2

now subtract the three right triangles

1/2* 2x5 + 1/2 * 1x3 + 1/2 * 1x6 = 9.5 units^2

18 - 9.5 = 8.5 units^2 < =====area of inscribed triangle in the rectangle

All proportions have <u>this</u> <u>form</u>:

$\sf{\dfrac{a}{b}=\dfrac{c}{d}}$ , Where $\sf{\dfrac{a}{b}}$ is equal to $\sf{\dfrac{c}{d}}$ .

If $\sf{\dfrac{a}{b}\neq\dfrac{c}{d}}$ , it's <u>not</u> a proportion.

_________________________

Here we have two pairs of numbers:

40,10 and 32,8.

Written As a <u>proportion</u>, they <em>look like</em> :

$\sf{\dfrac{40}{10}=\dfrac{32}{8}}$

Hope this made sense to you :)

Can someone please tell me why I got this wrong?

We have
f(x)=<span>−x</span>²<span>+ 5x + 6
g(x)=</span><span>3x − 2

we know that
f(x)=g(x)
the solution is the intersection both graphs

using a graph tool
see the attached figure

the solution are the points
(4,10)
and
(-2,-8)
