Answer:
OPTION A:
, where
.
Step-by-step explanation:
Given: 
Taking
common outside in the denominator, we get:

will get cancelled on the numerator and denominator, we get:

we know that the denominator can not be zero.
That means, 1 + 8x
0.


So, the answer is:
, where
.
Answer:
they have the same slopes
Step-by-step explanation:
lines that have the same slope never touch therefore they are parallel.
hence the answer is A
Answer:
f = e/2
Step-by-step explanation:
e = 2f
Switch sides.
2f = e
Divide both sides by 2.
f = e/2
-15x=-4x
We know that adding zero wouldn’t change the value
-15x=-4x+0
Now we can add 4x (since that’s the opposite of the negative sign) to the other side
-11x=0
0 divided by 11 is 0
x=0
Answer:
C
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius, here r = 12, hence
A = 4π × 12²
= 4π × 144 = 576π units² → C
