Answer:

x= -1/3 or x= -3/3

Step-by-step explanation:

Let's solve your equation step-by-step.

6x2+6x−1=−5x−4

Step 1: Subtract -5x-4 from both sides.

6x2+6x−1−(−5x−4)=−5x−4−(−5x−4)

6x2+11x+3=0

Step 2: Factor left side of equation.

(3x+1)(2x+3)=0

Step 3: Set factors equal to 0.

3x+1=0 or 2x+3=0

x= -1/3 or x= -3/3

The angle of elevation from the top of a house to a jet flying 2 miles above the house is x radians. If d represents the horizon

alisha [4.7K]

Answer:

d = 2cot(x) or d = 2/tan(x)

Step-by-step explanation:

The vertical distance from the jet to the top of the house represents the opposite side to the 'x' angle, while the horizontal distance, d, represents the adjacent side. Since we do not know the hypotenuse, the tangent and cotangent functions are the preferable choices:

$tan (x) = \frac{2}{d}\\d = \frac{2}{tan (x) }\\cot (x) = \frac{d}{2} \\d= 2cot(x)$

Therefore, the distance 'd' can be expressed as d = 2cot(x) or d = 2/tan(x).

Solve for X! Please help

WARRIOR [948]

The two given angles are vertical angles which mean they are the same:

9x + 72 = 4x + 112

Subtract 72 from bot sides:

9x = 4x + 40

Subtract 4x from both sides:

5x = 40

Divide both sides by 5:

X = 8
