Step-by-step explanation:
D) f(n) = 3 + 4(n-1)
3 = 1st term
4 = common difference among the terms
n = term number you are looking for.
To check: 3, 7, 11, 15, ...
f(1) = 3 + 4(1-1) = 3 + 4(0) = 3 + 0 = 3
f(2) = 3 + 4(2-1) = 3 + 4(1) = 3 + 4 = 7
f(3) = 3 + 4(3-1) = 3 + 4(2) = 3 + 8 = 11
f(4) = 3 + 4(4-1) = 3 + 4(3) = 3 + 12 = 15
The answer is: "
27.5 pages " ; or, write as: "
27
pages " .
____________________________________________________________5.5 pages / 12 minute = ? pages / 60 minutes;
12 * 5 = 60 ;
5.5 * 5 = ?
5.5 * 5 = 27.5
____________________________________________________________The answer is: "
27.5 pages " ; or, write as: "
27
pages " .

To take a root of a fraction, take the root of the numerator and denominator separately
Write the number in exponential form with a base of 2 to the second power
Write the number in exponential form with a base of 3 to the third power
Reduce the index of the radical and exponent with2
Reduce the index of the radical and exponent with 2
Then it’s gonna be 2/3 2over3
-3 2/3
Reduce the numbers with greatest common divisor 3
Then the answer will be -2
