The given expression is

Let's replace x = 7 and y = -2.

<h2>Therefore, the value of the expression is 20.</h2>
It is not parallel. The fact that there is more space between the lines on one side than the other (mk is shorter than nL) shows that the lines must be angled differently, and thus, would eventually intersect.
First box is 100 second is 4 third is 1500 4th box is 60 and last box is 1560
Well you need to find a common denominator which 30 is the closest one. 5/6 becomes 25/30, 9/10 becomes 27/30. 27/30+ 25/30 = 52/30. To simplify that you divide by 2 to get 26/15. It is no longer divisible to a whole number after that point.
