What is the perimeter of a square with sides that measure 2x + 3 units?
PtichkaEL [24]

Answer:

8x+12

Step-by-step explanation:

We know that squares have equal sides. To calculate perimeter, just add up all of the 4 sides.

2x+3+2x+3+2x=3+2x+3

Add like terms:

8x+12

You could also multiply by four:

4(2x+3)

Use distributive property:

8x+12

​ f(1)=72 f(n)=f(n−1)+9 ​ Find an explicit formula for f(n)
myrzilka [38]

a_{n} = 9n + 63

generate the first few terms using the recursive equation

f(1) = 72

f(2) = 72 + 9 = 81

f(3) = 81 + 9 = 90

f(4) = 90 + 9 = 99

the sequence is 72, 81, 90, 99, .....

This is an arithmetic sequence whose n th term formula is

a_{n} = a_{1} + (n - 1 )d

where a_{1} is the first term and d the common difference

d = 99 - 90 = 90 - 81 = 81 - 72 = 9 and a_{1} = 72

a_{n} = 72 + 9(n - 1) = 72 + 9n - 9 = 9n + 63 ← explicit formula
