Answer:

the answer will be D

Step-by-step explanation:

because (seven + x)*feet

the feet is 8 so

(7+x)*8

you distribute and it would be 56+8x

cause 8*7 is 56 & 8*x is 8x

so it would be D

We know the area is length * width.

So we know the length is 8 feet.

The width is 7 + x feet.

Multiply them:

8 * 7 + x.

56 + x.

So option D)

sorry, I misread the options! I meant D) not A)

What is the distance between the points (6,-7) and (1,5)

amid [387]

Answer: The distance is d = 13 .

Step-by-step explanation:

In order to find the distance between the two points, you need the distance formula:

$d = \sqrt{(x_{2} - x_{1})^2 +(y_{2} - y_{1})^2}$ where there is $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ .

-Use the those two points $(6,-7)$ and $(1,5)$ for this formula:

$d = \sqrt{(1 -6)^2 +(5 + 7)^2}$

-Then, you start solving:

$d = \sqrt{(1 -6)^2 +(5 + 7)^2}$

$d = \sqrt{(-5)^2 +(12)^2}$

$d = \sqrt{25 +144}$

$d = \sqrt{169}$

$d = 13$

So, therefore, the result is $d = 13$ .
