F(x)=-3.25x +22.41
f(-4.2)= 3.25(-4.2)+22.41 = 8.76
GCF is 4a^2
First find the GCF of whole numbers 16 and 12
16: 1, 2, 4, 8, 16
12: 1, 2, 3, 4, 6, 12
Gcf of 16 and 12 is 4
Now a^2 and a^4
Just look at the exponents
The highest you can take out of both of them is a^2
Now put the 4 and a^2 together
Answer is 4a^2
Let k = the constant amount added to the sequence since this
is an arithmetic sequence
x = missing
number
You have to formulate an equation based on the sequence:
6 + k = x or k = x – 6
x + k = 30
Substitute the value of k to the second formula:
x + x – 6 = 30
2x = 36
x = 18
Therefore, the missing number is 18.
