Question

If $k>0$

A: $(-1)(-2)(-k)$

B: $\left(1\right)\left(2\right)\left(k\right)$,

Then

• A. Quantity in A is greater than B.
• B. Quantity in B is greater than A.
• C. Both quantities are equal.
• D. The relationship cannot be determined from the information given.

Answer 1

The correct option is B Quantity in B is greater than A.

Given, $k>0$.
The quantity in $A$ is $(-1)(-2)(-k)=-2k$.
The quantity in $B$ is $2k$.
Since $k>0$, $2k>0$ and $-2k<0$. so, $2k>-2k$.

Therefore the quantity in $B$ is greater.
