Juliet decided to solve the quadratic x2 + 8x = 9. Which of the following steps is where she made her first mistake? x2 + 8x = 9 Step 1: x2 + 8x − 9 = 0 Step 2: (x + 9)(x − 1) = 0 Step 3: x = 9 and x = -1

Step-by-step explanation:

hello

last step is not good

from

(x+9)(x-1) = 0 we can write

<=> x+9 = 0 or x-1=0

<=> x = -9 or x = 1

so the solutions are -9 and 1

hope this helps

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
