Answer:

EF = 13 units

Step-by-step explanation:

Points E and F are the ends of segment EF.

Coordinates of E → (-7, -5)

Coordinates of F → (-2, 7)

Since, length of a segment joining points (x_1,y_1) and (x_2,y_2) is given by,

Length of segment = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}

Length of segment EF = \sqrt{(-7+2)^2+(-5-7)^2}

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

                                     = \sqrt{169}

                                     = 13

Therefore, length of segment EF is 13 units.

In the number 439 how is the value of three related to the value of nine
ratelena [41]

The 3 is in the tens place, meaning the value of the 3 is 3x10.

The 9 is in the ones place, meaning the value of the 9 is 9x1

So the place value of the 3 is ten times the value of the place value of the 9.
