-2(v - 2) = -3 – 2v

liq [111]

Answer:

no solution

Step-by-step explanation:

Given

- 2(v - 2) = - 3 - 2v ← distribute left side

- 2v + 4 = - 3 - 2v ( subtract 4 from both sides )

- 2v = - 7 - 2v ( add 2v to both sides )

0 = - 7 ← not possible

This indicates the equation has no solution

If n is a rational number then n2 is always less than n

stiv31 [10]

That easiliy false. You can prove this by observing that all integers are, in particular, rational numbers. So, for instance, you can think of 4 as $\frac{4}{1}$ , so $4 \in \mathbb{Z}\subset\mathbb{Q}$

And obviously, you have $4^2=16>4$

It is true that the square of every rational number between 0 and 1 is smaller than the number itself.

But since not all rational numbers are between 0 and 1, the general claim is false.
