Geometry Problem dont understand how to do it?

Question

FInd PD if the coordinate of P is -7 and the coordinate of D is -1

Answer 1

if you ever see a letter next to a letter of number next to a letter it emans mulitply

PD

P7

7P

they all have to be multiplied.

so in your case..

the equation is (-7)(-1)

when you multiply a negative by a negative .. it will always be a positive.. meaning you just multiply the number.

so.. if 7 times 1 is 7

-7 tims -1 is  7.

the answer to this problem is 7

Answer 2

big - small

-1 is bigger than -7.

-1 - (-7)

= -1 + 7

= 6

Answer 3

draw out a time line, and then count the difference between -7 and -1

or just take the minus (-) signs away completely and pretend it's 7 and 1.  then you just find the difference... so 7-1=?

yupp, 6

Answer 4

6
