Answer:

48√3 sq in

Step-by-step explanation:

The area is given by the formula ...

A = ab·sin(α)

where a and b are the side lengths, and α is the angle between them.

Here, the given values show the area to be ...

A = (12 in)(8 in)sin(120°) = (96 in²)(√3)/2

A = 48√3 in²

The area of the parallelogram is 48√3 in².

Answer:

X=-8 B if i can get brainliest that would be great

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(2x+1)=6x−12

(4)(2x)+(4)(1)=6x+−12(Distribute)

8x+4=6x+−12

8x+4=6x−12

Step 2: Subtract 6x from both sides.

8x+4−6x=6x−12−6x

2x+4=−12

Step 3: Subtract 4 from both sides.

2x+4−4=−12−4

2x=−16

Step 4: Divide both sides by 2.

2x/2=−16/2

x=−8

Answer:

x=−8
