0.07x = 35....with x being the cost of the stereo
84 inches. 0.00213 in kilometers
(4.18 × 9) = 37.62
10^-4 × 10^-4 = 10^-8
Then since you need to move the decimal over to make it in scientific notation, you add 1 to the 10^-8 , then you get 10^-7. The problem in scientific notation is 3.726×10^-7.
Area = length × width
45/4 = 9/2 × width
width = (45/4) ÷ (9/2)
= 5/2 feet
we have

Find the roots
Equate the function to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side.


Rewrite as perfect squares

Square root both sides




therefore
<u>the answer is</u>
