Step-by-step explanation:

We have to simplify the given expression:

1. 3x+2y-2x+23x+2y−2x+2

Combining the like terms,we get the second step as

2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)

Now, taking 'x' common from the first two terms, we get third step as:

3. (3-2)x+2y+2(3−2)x+2y+2

Now, simplifying the expressions among the like terms, we get fourth step as:

4. x+2y+2x+2y+2

The line needs to be 8.06 m long

Explanation

Given that the ladder is 7 feet tall and the bottom of the slide should be 4 m away from the ladder.

The ladder,slide and the ground connecting them makes the sides of a right angled triangle with ladder as the height and ground as the base.

base=4m

height=7m

hypotenuse can be determined using pythagoras law

$b^{2} +h^{2} =H^{2} \\x^{2} 4^{2}+ 7^{2}= H^{2} \\16+49=H^{2} \\H=\sqrt{65} \\=8.06 m$

This is correct, because it takes 27 minutes to get home so it will probably be about 30 minutes.
