Answer:
The number is -4
Step-by-step explanation:
This is a simple equation. To set this up, you will have to multiply the number (n) by -3 and then add 8 to it before setting it all equal to 20.
-3n+8=20
-3n=12
n=-4
Answer:
The explanation in the procedure
Step-by-step explanation:
we have
solve for c
For 
-----> Find the value of c
------> is not an integer
therefore
x cannot be a multiple of 6
Answer:
60 cm²
Step-by-step explanation:
Just divide the figure in parts and then find their areas separately. At last, find the area of the whole figure by adding the areas of the parts
F(x)=1/(x-3)^3
The denominator can't be equal to zero (we can't divide by zero), then:
(x-3)^3 different 0
cubic root both sides:
cubic root [ (x-3)^3 ] different cubic root (0)
x-3 different 0
Adding 3 both sides:
x-3+3 different 0+3
x different 3
Then the function f is not defined at x=3
Answer: Option <span>b) f is not defined at x= 3</span>
