The answer is D. 1.601 * 10^9

Answer:

Step-by-step explanation:

We start by finding what is inside the parenthesis, following the rules of pemdas we do 10 to the 6th power first, which comes out to be 1000000, we substitute this in instead of 10 to 6.

so we now have:

800.5x(2x1000000 )

Than finishing the parenthesis we multiply by 2

800.5x 2000000

than all you do is convert 800.5 to a decimal and 2000000 to an exponent, your teacher should have given you a chart or step by step directions for this part.

Have a great day!

Complete the table by providing justification for each step of the proof
exis [7]
4(x² - 2) = 28

1. Distribute the 4
4x² - 8 = -28

2. Plug in 3 and -3
4(3)² - 8 = 28
4(-3)² - 8 = 28

3. Square 3 and -3
4(9) - 8 = 28
4(9) - 8 = 28

28 = 28

The reason both answers are the same is because whenever you put a negative number to an even power, the result becomes positive because any negative multiplied by a negative number is always positive.
28 = 28
