The two points on the coordinate plane represent jane's house and her friend's house. find the distance between the houses.           a. √  8  units   b. 2√  10  units   c. √  10  units   d. 2√  17  units

The answer is 2, we need to use the distance between point formula; I recommend you search in the internet another examples.

Step-by-step explanation:

We need to calculate the distance between points, so we need to use the formula d=

You can use Janes house (-5,-2) or friends house like (3,-4) point 1 or 2, it is the same way.

when we substitute in the formula

:

d =

d=

d= =

We need to reduce this result, so we need to find two number wich on of those can we solve the square root, if we divide 68/4 we find:

d=

And 4 has exact square root result, so the result in:

2

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
