Answer:
Where's the question, please?
( y - 4 ) ( y² + 4 y + 16 ) = y³ + 4 y² + 16 y - 4 y² - 16 y - 64
The result is a polynomial of the form:
y³ + 4 y² + a y - 4 y² - a y + 64;
Answer: a = 16
F. 30 is the correct answer, for mean you just have to add all the ages together and divide by the number of customers
Answer:
Step-by-step explanation:
The range, in a layman language, is a set of values for which f(x) exist. Hence suppose our pre-image is 0-6,and since f(x)=20x+4 ,then
When x=0, f(x)= 4
When x=1, f(x)=24
When x=2, f(x)=44
When x=3, f(x)= 64
When x=4, f(x)=84
When x=5,f(x)=104
When x=6, f(x)=124
Hence the answer is B.
A' : -1, 3
B': 1, 2
C': 1, 5
