The product in scientific notation is 8*10^2

<h3>How to multiply and divide in scientific notation?</h3>

Here we want to find the product between 4*10^6 and 2*10^6, and write that in scientific notation.

First, we can solve the direct product:

(4*10^6)*(2*10^6) = (4*2)*(10^6*10^6)

Here we used the fact that we can multiply in any order we want.

Now we will use the property:

a^n*a^n = a^{n + m}

(4*2)*(10^6*10^6) = 8*10^{6 + 6} = 8*10^12

The correct option is the second one, counting from the top.

The length of a rectangle is 9 less than 4 less than the width. The perimeter is 143. Find the width and length.
damaskus [11]

The formula for perimeter is 2l+2w. Since we know l=(w-4)-9, we can substitute this into the formula.

l=w-13

2(w-13)+2w=143

2w-26+2w=143

4w=169

w=42.25 units

Hope this helps!
