Answer:
4x+9 if that's not what u needed I can graph it for you too
Answer:
1/18 x 9 x 1 = .5 cubic yards. Why would you ever waste time asking this....
Step-by-step explanation:
Answer:
x=-4 and x=4
Step-by-step explanation:
|x|= 4
the lines surrounding x means the x is positive and negative.
so
-x=4 and x=4
x=-4 and x=4
Use the z-score:
112 - 100
For 112, the z-score is --------------- = 12/15, or 0.8.
15
Next, find the AREA under the standard normal curve TO THE LEFT OF 0.8.
Use either a z-score table or a calculator for this purpose.
Using my calculator, I found that this area is 0.532. That places 112 in the 53rd percentile.
82 would be in a lower percentile: the 12th percentile.
Let me know if you have questions about how to use a calculator to do these calculations.
I think that the only polynomial that has a solution that are real numbers is:
B) x² + 4x + 3 = 0
(x + 3) (x + 1) → x² + 1x + 3x + 3 → x² + 4x + 3
(x+3) = 0 → x = -3
(x + 1) = 0 → x = -1
Real numbers are number that are whole numbers, rational and irrational numbers, positive and negative numbers, and even zero.
