The explicit rule for the number of marbles in 10th row is An= 12+ n-1.
<u>Step-by-step explanation</u>:
- Total number of rows = 10 rows
- The number of marbles in the 1st row = 12 marbles
- One marble is added to each successive row
Therefore, for the remaining 9 rows out 10 rows ⇒ 9 marbles are added.
- The number of marbles in the 10th row = 12+9 = 21 marbles.
- The explicit rule is An = 12 + n-1
For n= 10, then
⇒ A10 = 12 + (10-1)
⇒ A10 =12+9 = 21

(g + f)(x)
g(x) + f(x)
x - 1 + x^2 + 4
x^2 + x + 3
(g - h)(x)
g(x) - h(x)
3x + 1 - (2x - 2)
3x + 1 - 2x + 2
