−2(−3x+4)+3x−3=−29 what does x equal
gogolik [260]

Answer:

x = −2

Step-by-step explanation:

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

−2(−3x+4)+3x−3=−29

Step 1: Simplify both sides of the equation.

−2(−3x+4)+3x−3=−29

(−2)(−3x)+(−2)(4)+3x+−3=−29(Distribute)

6x+−8+3x+−3=−29

(6x+3x)+(−8+−3)=−29(Combine Like Terms)

9x+−11=−29

9x−11=−29

Step 2: Add 11 to both sides.

9x−11+11=−29+11

9x=−18

Step 3: Divide both sides by 9.

9x /9  =  −18 /9

x=−2

I hope this helps!!!

1035.33156649 meters high is the helicopter flying over the building.

Given that, an observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a 49° angle of elevation.

We need to find how high is the helicopter flying over the building.

<h3>How to find the height of the building using trigonometry?</h3>

To measure the heights and distances of different objects, we use trigonometric ratios.

Here, use the Tangent rule to calculate the height of the building.

tan(angle) = opposite/adjacent

Now, tan 49°=h/900

⇒h=1035.33156649 meters

Therefore, 1035.33156649 meters high is the helicopter flying over the building.
