Please help.. i’ll give you brainliest and a thanks! the answer choices are 16 36 28 26 22 42..

Area= 26

Step-by-step explanation:

We can reduce this shape into 3 rectangles.

Rectangle 1: length=4 width=2

Rectangle 2: length=10 width=1

Rectangle 3: length=4 width=2

The formula for area of a rectangle is: l×w (length time width)

Now, just multiply!

4×2= 8

10×1= 10

4×2= 8

Add them all up.

8+10+8= 26

So, the area is 26cm^2.

Hope this helps!

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
