The distance between the points (5, -2) and (-7, 3) is

irinina [24]

For this case we have that the distance between two points is given by:

$d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}$

We have the points:

$(x_ {1}, y_ {1}) = (5, -2)\\(x_ {2}, y_ {2}) = (- 7,3)$

Substituting:

$d = \sqrt {(- 7-5) ^ 2 + (3 - (- 2)) ^ 2}\\d = \sqrt {(- 7-5) ^ 2 + (3 + 2) ^ 2}\\d = \sqrt {(- 12) ^ 2 + (5) ^ 2}\\d = \sqrt {144 + 25}\\d = \sqrt {169}\\d = 13$

Thus, the distance between the points is 13

Answer:

$d = 13$

2(2x + 4) + 2(x - 7) = 78. Determine the side lengths of this rectangle.

sp2606 [1]

$2(2x + 4) + 2(x - 7) = 78$

$4x + 8 + 2x - 14 = 78$

$(4x + 2x) + (8 - 14) = 78$

$6x - 6 = 78$

$6x = 78 + 6$

$6x = 84$

$x = \frac{84}{6}$

$x = 14$

Some body help me with 5x + 7 + 2x

ELEN [110]

Answer:

14x

Step-by-step explanation:

You have two like terms (numbers with the same letter) so you are going to put those aside for a moment.

Add 5+7+2 and you get 14.

Then, You put the unknown number (x) just beside the 14 to know you are multiplying x by 14 until you find the value.

14x Is your answer

Calculate the slope of the points (2,1) and (3,4). show all your work.

Angelina_Jolie [31]

Answer:

The slope of this line would be 3.

Step-by-step explanation:

To find the slope of any line, use the slope formula and the points given.

m(slope) = (y2 - y1)/(x2 - x1)

m = (4 - 1)/(3 - 2)

m = 3/1

m = 3
