If a, b, c are in A. P., and a², b²,c² are in H. P. (a ≠ b ≠ c) then: (A) a 2b, c are in G. P
(B) a, b, care in H. P
(C) a, b, -c/2 are in G. P.
(D) -a/2 , b, c are in GP
(More than one are correct, and please try to explain it)​

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this

step-by-step explanation:

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
