Answer: b. four fifths plus two fourths

Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.

Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.

4/5  <em>20/5 = 4    4×4 = 16   so 4/5 is equivalent to 16/20</em>

2/4   <em>20/4 = 5    5×2 = 10   so  2/4 is equivalent to 10/20   </em>

Add:    16/20 + 10/20 = 26/20

Ok to start divide 680 by 170 which = 4

it doubles 50 each time so it would have doubled 4 times 50+50+50+50+50+50+50+50

Help ^^^ use picture above
aalyn [17]
The question reminds you of all the tools you need:

It says ...

"Opposite angles are equal."
So the upper right angle is x+40 just like the bottom left,
and the bottom right angle is 3x+20 just like the upper left.

And it says ...

"The sum of all angles is 360°."
You know what each of the four angles is, so you can addum all up,
set the sum equal to 360, find out what number ' x ' is, and then
use that to find the size of every angle.

ANSWER

34 {units}^{2}

EXPLANATION

The width of the rectangle is |AB|

A(-1,4) and B(3,3)

We use the distance formula,

d =  \sqrt{ {(x_2-x_1)}^{2} + {(y_2-y_1)}^{2} }

This implies that,.

d =  \sqrt{ {(3- - 1)}^{2} + {(3 - 4)}^{2} }

d =  \sqrt{ {(4)}^{2} + {( - 1)}^{2} }

d =  \sqrt{ 16+ 1 }

d = \sqrt{17}

The length is BC

C(1,-5) and B(3,3)

d =  \sqrt{ {(3- 1)}^{2} + {(3 -  - 5)}^{2} }

d =  \sqrt{ {2}^{2} + {(8)}^{2} }

d =  \sqrt{4 + 64 }

d = \sqrt{68}

d = 2 \sqrt{17}

The area is

= l \times w

= 2 \sqrt{17}  \times  \sqrt{17}

2 \times 17 = 34 {units}^{2}
