Answer:
the answer is 67!! I think I asked my teacher and thats what they said.
Step-by-step explanation:
1. X/Y = Z
if x = 6, y = 2, then z = 3, not even
if x = 6, y = 3, then z = 2, even
<span>2. Z=XY </span>
so (z)^2 = 2*k (because x*y*z = 2k, where k is an integer)
<span>Sufficient, as if square of an integer is even ,then the integer is even</span>
consec numbers are right after each other like 2, 3, 4
now if
2 is x
3 is x+1
4 is x+2
same for all consec numbers
=x +x+1 +x+2
Now this one says, 2 times the second and 3 times the third so its
=x +2(x+1) +3(x+2)
now the second part
x +2(x+1) +3(x+2) = 170
x + 2x + 2 + 3x + 6 = 170
6x + 8 = 170
6x = 170 -8
6x = 162
x = 27
so the numbers are 27, 28 and 29

So,
First, notice that all of the answer options are in completed square form. So all we have to do is complete the square for the initial equation and see which equation it matches.

Isolate the constant term.

Add the necessary amount to both sides (halve the x term and square it).

Factor the completed square.

This equation is identical to the equation in option B.
The correct answer is B.
