x³+2x²-6x-12=x²•(x+2)-6(x+2)=(x+2)•(x²-6)
Provide a picture or answer choices and I can answer the question of
Answer: =
Step-by-step explanation:
let the number be x , then :
six added to twice the sum of a number and four means :
one half of the difference of three and the number means :
combining the two , we have
=
Answer:
The rate of change is ft^(2)/min
Step-by-step explanation:
The area of a circle is given by the following equation:
To solve this question, we have to realize the implicit differentiation in function of t. We have two variables, A and r. So
We have that:
.
We want to find
So
Since the area is in square feet, the rate of change is in ft^(2)/min.
So the rate of change is ft^(2)/min
There are 2 sides to a coin so 2 outcomes so far
then 3 balls to chose from so 3 times as many
so
h=heads
t=tails
r=red
b=blue
g=green
I will put them into slots where column 1 is coins and column 2 is color of ball
1, 2
h, r
h, b
h, g
t, r
t, b
t, g
there are 6 possible outcomes
another way is to multiply all the choices together so 2 coin choices and 3 ball choices so 2 times 3=6
