Answer:
19.04
Step-by-step explanation:
find the length of AB,BC,CD , and AD
distance=√(x2-x1)^2+(y2-y1)^2
A(-3,5), B(2,6),C(0,2),D(-5,1)
line AB :d=√(2−(−3))^2+(6−6)^2
AB=5
BC=d=√(0−2)^2+(2−6)^2=√20=2√5
CD:√26
DA:√20
perimeter=AB+BC+CD+DA=5+√20+√20+√26=19.04
Answer:0.11 of a mile
Step-by-step explanation:First thing you would do was divide 45 by 5 to get nine so he runs 1 mile every nine minutes so then I will divide 1 by 9 to get 0.11 of a mile but I don’t know if that’s what it means
I think the answer is 3
9+12=m or 9+12=21
this is because when we start with m-9=12 we know that m is supposed to be the sum of 9 and 12.
if we check our work we will see this
9+12=21
m-9=12
21-9=12
