Answer:

speed of light is 3 x 10^{8} meters per second.

Step-by-step explanation:

Given : The speed of light is 3 x 10^{5} kilometers per second.

To find :  What is that in standard form.

Solution : We have given 3 x 10^{5} kilometers per second.

First we convert it in to meter per sec.

We can write  

3 x 10^{5} = 300000 kilometer per second .

We know that 1 km = 1000 meter.

Then 300000000 meter per second

Now,   3 x 10^{8} meter per second.

Therefore,  speed of light is 3 x 10^{8} meters per second.

Solve for x:<br> 4x – 7 = 8x + 33
Lera25 [3.4K]

Answer:

x = 10

Step-by-step explanation:

Hey there!

To solve this question we will use PEMDAS (order of operations)

4x−7=8x+33

Subtract 8x from both sides.

4x−7−8x=33

Combine 4x and −8x to get −4x.

−4x−7=33

Add 7 to both sides.

−4x=33+7

Add 33 and 7 to get 40.

−4x=40

Divide both sides by −4.

x= 40/-4

Divide 40 by −4 to get −10.

x=−10

There is a square and a triangle
the area of a square is 
A = b * h 
A = 2*2
A = 4

the area of the triangle is 
A = (b*h)/2
A = (2 *2)/2
A = 4/2
A = 2

Now we add them up to find the total area
4 + 2 = 6
The shape has an area of 6 units^2
