netineya [11]3 years ago
8 0

Answer:

x

Step-by-step explanation:

So you start by putting the like terms together which will be

9x-3x=6x

You then open the brackets at the other part of the question

3 x 2x+3 x 4=6x+12

The question now becomes

6x +12=6x+12

Take 12 to the other side and minus.You will be left with

6x=6x

Simplify and your left with x which is your answer

An object in a simulation accelerates
notsponge [240]

Observe the graph below. This graph represents the scenario.

The question is ill formated, the complete question is

In a simulation, a moving object accelerates from rest to 4 meters per second in 2 seconds. For the following three seconds, it increases linearly until it reaches a speed of 10 meters per second. Following three seconds at that speed (acceleration = 0), the item progressively decelerates until it comes to rest two seconds later. Draw the graph of this scenario for 10 seconds?

I'll describe how the graph may show.

It will move diagonally upward from time 0 to 2 seconds until it reaches the y axis at a speed of 4 m/s.

Then, from 2 to 5, the position will move up diagonally until it reaches the y axis at a speed of 10 m/s.

The next 5 to 8 seconds will be horizontal.

After that, it will descend diagonally.

Observe the graph below. This graph represents the scenario.

otez555 [7]

Answer:

The answer to your question is: 30 in

Step-by-step explanation:

Data

1 piece

Width = 4 in

Length = 6 in

2 piece

Width = 6 inches

Proportions

                               4 : 6 :: 6 : x

                                x = (6 x 6) / 4

                               x = 9

Perimeter = 2(base) + 2(height)

                 = 2(9) + 2(6)

                 = 18 + 12

                 = 30 in
