Answer:
d = 3 sqrt(2)
Step-by-step explanation:
To find the distance between two points we can use the formula
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
d = sqrt( ( -1 - -4) ^2 + (9-6)^2)
d = sqrt( (-1+4)^2 + 3^2)
d = sqrt( 3^2+3^2)
d = sqrt(9+9)
d = sqrt(18)
Simplifying
d = sqrt(9*2)
3,3
absolute both values
|-4,6|=4,6
|-1,9|=1,9
4-1=3
9-6=3
the answer is x=15
75/5=15
120/8=15
180/12=15
Hope this helps some.
