To work out standard form, you must count the amount of numbers the decimal point must jump to get a number which is less than 10.
As an example, the number 120 would be 1.2x10^2
This is because 120 can also be written as 120.0, and to make the number smaller than 10 (1.2) the decimal point has to move 2 places to the left making it x10^2.
a) There are 1000g in a Kg, meaning there are 7200000g there. In standard form, it has to be a decimal x10 to a power. 7200000 becomes 7.2x10^6
b) 0.0006 will be 6.0x10^-4
c) 7200000/0.0006=12000000000 which in standard form is 1.2x10^10

Answer:

The expression 7x represents the height of the container.

Step-by-step explanation:

From the question:

We are being informed that; if the length of the container is half of a foot longer than its width.

Let the width be x;

Then the length of the container can now be ; x+1/2

We all known that the volume of a rectangular prism is : V= l×w×h

here;

l = length

w = width

h = height

If we rewrite the given expression :

$\mathbf{7x^3+3.5x^2}$ ;

Then we factor we make a similar coefficient of the above equation, the remaining entities left in the parenthesis should be a linear term with a leading coefficient of 1 to match the expression for the length of the container.

i.e

$\mathbf{7x^3+3.5x^2}} \\ \\\mathbf{7x^2(x+1/2)} \\ \\\mathbf{7*x*x*(x+1/2)}$
