Let x and y be vectors in r3. prove that if x + yis
orthogonal to x - y then
x
=
y
. give a geometrical interpretation of this result.

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108

Which expression is not a polynomial?
