Answer:
A. 2(x + 9) = 8
Step-by-step explanation:
To solve this problem, we proceed as follows:
- We call "x" the number picked up by Amy:

- Amy then adds 9 to this number, so we get:

- Then, we multiply this sum by 2, so we get:

- Finally, Amy says that this number is equal to 8:

So the correct equation is
A. 2(x + 9) = 8
We can even solve it to find the number. We get:

There is a pattern of 8 after each number (b)
For 8, it's 6.2 . For 9, it's 7.0 (or 7)
Answer:
-22,-4,4,37,69
Step-by-step explanation:
The greatest negative number (-22) is always smaller than the smaller negative number (-4).
2 and 7 because it will stay constant
Y = 0 so
x^2 + 6x - 40 = 0
(x +10)(x - 4) = 0
x+10 = 0; x = -10
x - 4 = 0; x = 4
answer is C. x = -10 and x = 4
