let the unknown side be x , so we have :

25^2 = 20^2 + x^2

625 = 400 + x^2

x^2 = 625 - 400

x^2 = 225

x = √225

x = 15

What is equavilent to (10x+7r-r^(2))+(-6r^(2)-18+5r)
mote1985 [20]

Answer:

−7r^(2)+12r+10x−18

Step-by-step explanation:

Grab the original equation: 10x+7r−r^(2)−6r^(2)−18+5r

For subtraction bits, treat them as negatives: 10x+7r+−r^(2)+−6r^(2)+−18+5r

Combine like terms: (−r^2+−6r^2)+(7r+5r)+(10x)+(−18)

Simplify that, and you get your final answer: −7r^(2)+12r+10x+−18

Question
dezoksy [38]

Answer:

  The equations of the lines are y=3 and y=8.

  Parallel lines have equal slopes, so if the slopes are opposites, the slopes must be 0.

  A line with this slope and passing through (7, 3) has equation y=3.

Step-by-step explanation:

The above answer statements pretty much speak for themselves. The only opposite numbers that are equal are 0 and -0 = 0, so the slopes must be 0.

A line with a zero slope has a constant y-value, so is of the form ...

  y = constant

If it goes through a point with a y-coordinate of 3, then the constant must be 3. The line is ...

  y = 3

___

If the sum of two numbers is 11 and one of them is 3, the other is 8. So, the parallel line has equation y = 8.
