Answer:
The answer is 4n + 16
Step-by-step explanation:
N is the number of days that pass by. Each day Sam gets 4 more, meaning you would multiply the number of days by 4, before adding that number to the original number of pennies, which was 16.
70 flowers were planted in all.
Step-by-step explanation:
Let,
Tulips = t
Daises = d
Lilies = l
Total tulips planted = 42
She planted 2 times as many tulips as daises.
t=2d
Putting t=42

Dividing both sides by 2

And 3 times as many daisies as lilies.
d=3l
Putting d=21

Dividing both sides by 3

Total flowers planted = Tulips + Daisies + Lilies
Total flowers planted = 42 + 21 + 7 = 70
70 flowers were planted in all.

The perimeter of a square is the sum of its sides.
Then the perimeter is
P = 4L
Clearing the side we have:
L = (P / 4)
L = (12x + 52) / 4
L = 3x + 13
answer:
The side length of the square is 3x + 13 units
