Answer:

For example: 0=1 This is false because we know zero can't equal one. Therefore we can conclude that the problem has no solution. You can solve this as you would any other equation. 13x−5(x−4)=8x+513x−5x+20=8x+58x+20=8x+58x−8x+20=8x−8x+520=5 We see this is a false statement because 20 does not equal 5.

Simplify.

<h3>Answer: $3\sqrt{7}$ </h3>

3*sqrt(7)

3 times the square root of 7

====================================================

Explanation:

I'm assuming the V stands for square root. You can write sqrt(63).

$\sqrt{63} = \sqrt{9*7}\\\\\sqrt{63} = \sqrt{9}*\sqrt{7}\\\\\sqrt{63} = 3\sqrt{7}$

The idea is to factor 63 in such a way that one factor is the largest perfect square possible, that way we can pull the root apart to simplify as shown above. The rule I used for the second step is $\sqrt{x*y} = \sqrt{x}*\sqrt{y}$
