Answer:

x=−7

Step-by-step explanation:

Apply the distributive property.

3x−2(3x)−2⋅−2=2(4−x)+33x-2(3x)-2⋅-2=2(4-x)+3

Multiply 33 by −2-2.

3x−6x−2⋅−2=2(4−x)+33x-6x-2⋅-2=2(4-x)+3

Multiply −2-2 by −2-2.

3x−6x+4=2(4−x)+33x-6x+4=2(4-x)+3

Subtract 6x6x from 3x3x.

−3x+4=2(4−x)+3

You need to remove a tree from your front yard. You have climbed the tree and trimmed off the branches, and you are now ready to

ValentinkaMS [17]

Answer:

26 feet

Step-by-step explanation:

Let the length of the required wire =l

The height of the tree =24 cm

We want the tree to fall to the ground 10 feet away from the base.

Ths problem forms a right triangle which I have drawn and attached below.

To determine the length of the wire l required, we use Pythagoras theorem to solve for the hypotenuse of the right triangle.

$B$y Pythagoras theorem: Hypotenuse^2=Opposite^2+Adjacent^2\\$Therefore:\\l^2=24^2+10^2\\l^2=676\\$Take the square root of both sides\\l=\sqrt{676}\\ l=26$ feet$

Thw wire must be 26 feet long to reach the ground.
