Answer: =80/11

Step-by-step explanation:x=80-10x

We move all terms to the left:

x-(80-10x)=0

We add all the numbers together, and all the variables

x-(-10x+80)=0

We get rid of parentheses

x+10x-80=0

We add all the numbers together, and all the variables

11x-80=0

We move all terms containing x to the left, all other terms to the right

11x=80

x=80/11

x=7+3/11

The coordinates of the vertices for rectangle ABCD are A (2,4), B (6,10), C (9,8) and D (5,2). What

sweet [91]

Answer:

D. $\sqrt{65}$

Step-by-step explanation:

The computation of the length of a diagonal (AC or BD) of the rectangle is shown below:

As we know that

The Diagonal length of AC is

$= (x_2 - x_1)^2 + (y_2 - y_1)^2\\\\= (9 -2)^2 + (8 - 4)^2\\\\= (7)^2 + (4)^2$

$= \sqrt{49 + 16}\\\\= \sqrt{65}$

Therefore correct option is D.
