= g^2(2g - 1) - 4(2g - 1)
=(2g - 1)(g^2 - 4)
= (2g - 1)(g + 2)(g - 2)</span>
Answer:
No, she used the diameter instead of the radius measure.
Step-by-step explanation:
we know that
The volume of the sphere is equal to
we have
----> the radius is half the diameter
substitute
Answer:just tryna get points don't mind me
Step-by-step explanation:
....
The answer to <span>-7(k+9)=9(k-5)-14k is
k = -9
</span>-7(k+9)=9(k-5)-14k
Use the distributive property to distribute the -7 to (k+9) and 9 to (k-5)
-7(k+9)=9(k-5)-14k
-7k - 63 = 9k - 45 - 14k
Now lets get all our constants on one side of the equal sign and all our terms such as 9k and 4k on a side by their self
-7k - 63 = 9k - 45 - 14k
-7k - 63 + 45 = 9k - 45 + 45 - 14k
-7k - 18 = 9k - 14k
Now lets get that -7k on the right side
-7k + 7k - 18 = 9k - 14k + 7k
-18 = 9k - 14k + 7k
Now lets do the math for 9k - 14k + 7k and solve for k
-18 = 9k - 14k + 7k
-18 = 2k
-18 / 2 = 2k / 2
-9 = k
k = -9
A. 80
