Answer:

if you are solving for o it is −x2−11x−6

                                                   6x2

if you are solving for x it is im not sure sorry  

Step-by-step explanation:

−9x=x2+x−4x2+x+4x2−x+6ox2+x+6

Step 1: Flip the equation.

6ox2+x2+2x+6=−9x

Step 2: Add -x^2 to both sides.

6ox2+x2+2x+6+−x2=−9x+−x2

6ox2+2x+6=−x2−9x

Step 3: Add -2x to both sides.

6ox2+2x+6+−2x=−x2−9x+−2x

6ox2+6=−x2−11x

Step 4: Add -6 to both sides.

6ox2+6+−6=−x2−11x+−6

6ox2=−x2−11x−6

Step 5: Divide both sides by 6x^2.

6ox2                −x2−11x−6

6x2                      6x2

Answer:

o= −x2−11x−6

          6x2

Find the length of the side of rhoumbus whose diagonals are of length 6cm and 8cm.​
Artist 52 [7]

Answer:

In a rhombus, the diagonals bisect at right angles. That means half the diagonals form a right angle triangle then we can try the Pythagorean theorem. so -

one side of triangle =  6/2 =3 (half of the diagonal)

other side = 8/2 = 4

a^2 + b^2 = c2

3 ^2 + 4^2 = c^2

9+16 = c^2

c^2=25

c = \sqrt{25} = 5

the hypothenus forms one side of the rhombus and here the hypothenus is 5, so the lenght of a side is 5 !

While taking a ride in a hot-air balloon in Napa Valley, Francisco wonders how high he is. To find out, he chooses a landmark th
Delicious77 [7]

Answer:the height of the balloon is 670.244 feet

Step-by-step explanation:

The right angle triangle BLD represents the scenario.

h represents the height of the balloon.

We would apply trigonometric ratio to determine h.

Tan # = opposite side/adjacent side

Looking at triangle LCD,

# = 61 degrees

h = opposite side

x = adjacent side

Tan 61 = h/x

1.7321 = h/x

h = 1.7321x

Looking at triangle LBD,

# = 54 degrees

h = opposite side

x + 100 = adjacent side

Tan 54 = h/x + 100

1.3764 = h/x + 100

h = 1.3764(x + 100)

Therefore,

1.7321x = 1.3764(x + 100)

1.7321x = 1.3764x + 137.64

137.64 = 1.7321x - 1.3764x

137.64 = 0.3557x

x = 137.64/0.3557 = 386.955

h = 1.7321x = 386.955 × 1.7321

h = 670.244 feet
