Answer:
d(A,B)=1
Step-by-step explanation:
To find distance between points A(xA,yA) and B(xB,yB), we use formula:
d(A,B)=(xB−xA)2+(yB−yA)2−−−−−−−−−−−−−−−−−−−√
In this example: xA=3 , yA=5 , xB=3 and yB=6 so:
d(A,B)d(A,B)d(A,B)=(3−3)2+(6−5)2−−−−−−−−−−−−−−−√=0+1−−−−√=1
Answer:
<em>2(x) + 2(x + 3) = 90 </em>
Step-by-step explanation:
Width: x inch.
Length: (x + 3) inch.
P = 2 
+ 2 
P = <em>2(x) + 2(x + 3) = 90</em>
