Answer:
24x^2 -10x - 25
Step-by-step explanation:
24x^2 + 20x - 30x - 25
24^2 -10x - 25
Answer:
x = -8.5
Step-by-step explanation:
Let's rearrange the question to find x :)
-8x + 6x + 10 - 8 = 19
-2x + 2 = 19
-2 -2
-2x = 17
/-2 /-2
x = -8.5
Answer:
128 feet
Step-by-step explanation:
![t = 2\pi \sqrt{\frac{l}{32} }](https://tex.z-dn.net/?f=t%20%3D%202%5Cpi%20%5Csqrt%7B%5Cfrac%7Bl%7D%7B32%7D%20%7D%20)
So now we will substitute the values of T and π into the equation.
![12.56 = 2 \times 3.14 \sqrt{ \frac{l}{32} }](https://tex.z-dn.net/?f=12.56%20%3D%202%20%5Ctimes%203.14%20%5Csqrt%7B%20%5Cfrac%7Bl%7D%7B32%7D%20%7D%20)
![12.56 = 6.28 \sqrt{ \frac{l}{32} }](https://tex.z-dn.net/?f=12.56%20%3D%206.28%20%5Csqrt%7B%20%5Cfrac%7Bl%7D%7B32%7D%20%7D%20)
Divide both sides by 6.28
![2 = \sqrt{ \frac{l}{32} }](https://tex.z-dn.net/?f=2%20%3D%20%20%5Csqrt%7B%20%5Cfrac%7Bl%7D%7B32%7D%20%7D%20)
Square both sides.
![4 = \frac{l}{32}](https://tex.z-dn.net/?f=4%20%3D%20%20%5Cfrac%7Bl%7D%7B32%7D%20)
Multiply both sides by 32
![l = 4 \times 32 \\ l = 128 \: feets](https://tex.z-dn.net/?f=l%20%3D%204%20%5Ctimes%2032%20%5C%5C%20l%20%3D%20128%20%5C%3A%20feets)
The last one is not scientific notation because the 25.67 is greater than 10
Answer:
C. AAS
Step-by-step explanation:
they share 2 angles(A) you can tell by the markings and they share that one side
by this point you have 2 options left
ASA
or
AAS
the angles are right next to each other so it's AAS
