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

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
