Solve the equation 2(9x-6)=6(3x-2)+2
weqwewe [10]

Answer:

There are no solutions.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(9x−6)=6(3x−2)+2

(2)(9x)+(2)(−6)=(6)(3x)+(6)(−2)+2(Distribute)

18x+−12=18x+−12+2

18x−12=(18x)+(−12+2)(Combine Like Terms)

18x−12=18x+−10

18x−12=18x−10

Step 2: Subtract 18x from both sides.

18x−12−18x=18x−10−18x

−12=−10

Step 3: Add 12 to both sides.

−12+12=−10+12

0=2

A goat enclosure is in the shape of a right triangle. One leg of the enclosure is built against the side of the barn. The other
Sonbull [250]

Answer:

The lengths are

8 + 8[root]3 , 12 + 8[root]3 and 20 + 8[root]3.

Step-by-step explanation:

Let the side against the barn be xft

We were told that the adjacent side is 4ft more than the side against the barn. This means it has a length of (x + 4)ft.

Lastly, we are told that the hypotenuse is 8ft longer than the side along the barn I.e (x + 4 + 8)ft = ( x + 12)ft.

Since the three lengths form a triangle, the square of the hypotenuse equals the square of the adjacent side plus the square of the opposite side. This is the pythagoras' theorem.

Mathematically, this can be written as follows:

(x + 12)^2 = x^2 + (x + 4)^2

This yields x^2 + 24x + 144 = x^2 + x^2 + 8x + 16

x^2 + 24x + 144 = 2x^2 + 8x + 16

Rearranging this will yield:

x^2 - 16x - 128 = 0

Using the quadratic formula yields the following values for x :

8 - 8[root]3 and 8 + 8[root 3]

Since the first is negative, we discard it and the only correct value of x is 8 + 8[root]3

Now the other length is 12 + 8[root]3 and 20 + 8[root]3.
