Answer:

8x-4

Step-by-step explanation:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

3x - 5 + 5x +1

Next, group like terms:

Зх + 5х — 5 + 1

Now, combine like terms:

(3 + 5)x + ( – 5 + 1)

8x + ( – 4)

8х — 4

What is the distance between the points ( 19, 4) and (11, 12)?

Olenka [21]

D = $\sqrt{(x_{2}- x_{1})^{2}+ (y_{2} -y_{1})^{2}}$
D = √(11-19)²+(12-4)²
D = √(-8)²+(8)²
D = √64+64
D = √128
D ≈ 11.3137

I will give branliest

Evgesh-ka [11]

Step-by-step explanation:

Height of ladder = 12ft .

Here perpendicular is height to which it reaches .

When angle is 30⁰ :-

=> sin 30⁰ = H/12

=> ½ = H/12

=> H = 12/2

=> H = 6m ( ans )

When Angle is 45⁰ :-

=> sin45⁰ = H/12

=> 1/√2 = H/12

=> H = 6*√2*√2/√2

=> H = 6√2 m ( ans )

When angle is 60⁰ :-

=> sin60⁰ = H/12

=> √3/2 = H/12

=> H = 12 *√3/2

=> H = 6√3 ( ans )

hope it helped !
