Contradictions usually mean they go against established rules. Squaring a negative number is one example if it is in math. But just think of anything that goes against what is known.
The slope is 20/13. Yes, the slope is steeper because without the lip on the slide you would travel downward faster.

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to combine the like terms
From given expression,

By distributive property,
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
a(b + c) = ab + bc
Therefore,
Solve for brackets using distributive property

Add 1/7 and 6/7

Thus the equivalent expression is found
