Answer: -4

Step-by-step explanation:

3x-2(6x-3)=42

3x - 12x + 6 = 42

-9x + 6 = 42

-9x = 42 - 6

x = -36/9 = -4

Answer:

x = -4

Step-by-step explanation:

3x-2(6x-3)=42

Distribute

3x -12x+6 = 42

Combine like terms

-9x+6 = 42

Subtract 6 from each side

-9x+6-6 = 42-6

-9x = 36

Divide each side by -9

-9x/-9 = 36/-9

x = -4

zaharov [31]

The distance between the building and the ladder is 34.876 foot.

<h3>What is a Right Triangle?</h3>

A triangle in which one of the angle measure is equal to 90 degree is called a right triangle.

The ladder forms a right triangle with the building and the ground,

The length of the triangle is 40 foot

The angle made by the ladder is 29.32 degree

By using Trigonometric Ratios

cos 29.32 = Base /  Hypotenuse

cos 29.32 = Base / 40

0.8718 × 40 = Base

Base = 34.876 foot

Base is the distance between the building and the ladder.

Base of the ladder = 34.876 foot

-3(x + 4) = (-x - 1)
zaharov [31]

Answer:

x=-5.5

Step-by-step explanation:

-3(x+4)=(-x-1)

1. Distribute

-3x+(-12)=-x-1

2. Simplify

-3x-12=-x-1

-2x-12=-1

-2x=11

x=-11/2

x=-5.5
