Answer:
Adding by 4 each time
Step-by-step explanation:
ummm it think so
a+b+c=9 and a2+b2+c2=35 then by using identity
(a+b+c)2=a2+b2+c2+2ab+2bc+2ca,we get the answer 9x9=35+2(ab+bc+ca)
2(ab+bc+ca)=9x9-35
2(ab+bc+ca) =81-35then we get ab+bc+ca=46/2 so ab+bc+ca=23
(5)
The given two points are:
A(3,k) and B(h,4)
Now, using the distance formula that is=.
In the given points, ,, and , thus,
=
which is the required equation, hence option 5 is correct.
