X² + 4x - 8 = 5
This is a simple quadratic equation. Let's move everything to the left side to start:
x² + 4x - 8 - 5 = 5 - 5
Now we have:
x² + 4x - 13 = 0
In a quadratic equation, x =
Therefore, we plug in a = 1, b = 4, and c = -13, and we find that x = -2 - sqrt{17} OR -2 + sqrt{17}.
There is no picture below lol
Answer:
No.
standard deviation kind of works like absolute value. think of it that way. absolute value is just distance from zero and standard deviation is just distance from the mean.
Answer:
I'm not completely sure but in my opinion I think the answer is that the Associated store has the better buy for oranges! :-)
Step-by-step explanation:
Because they have $3.00 for five pounds and the shoprite store has 2.59 for 4 pounds, but if you where to buy a fifth one at the Shoprite store then you would have to pay more for 5 pounds of oranges then you would for the 5 pounds of oranges at the Associated store.
Hope this helps! Please mark me brainliest! :-)))))))
Step-by-step explanation:
looking at the diagram, AC is the hypotenuse, AD is the adjacent and CD is the opposite (based on the position of the angle).
Since you are looking for CD, you would use Sine (SOHCAHTOA). Sine would be opposite over hypotenuse and following the same procedure, you will the cross multiply to get your answer
