121 slabs . How many slabs will she need to lay in each row to make a square
netineya [11]

She needs to lay 11 slabs on each row to make a square

<h3>How to determine the number of slabs in each row?</h3>

The total number of slabs is given as:

Total = 121 slabs

Let this represent the area of the slab.

The area of a square is calculated as:

Area = Length^2

Substitute the known values in the above equation

Length^2 = 121

Take the square root of both sides

Length = 11

Hence, she needs to lay 11 slabs on each row to make a square

For the following geometric sequence find the explicit formula {1,-3,9,...}
Zarrin [17]
The first term of this series (a+1) is 1 and the common ratio (r) is -3.

Thus, the explicit formula is a_n = 1*(-3)^(n-1).

Must check this!  suppose we try to calculate the 3rd term.  Then n = 3.

a_3 = 1*(-3)^(3-1) = (-3)^2 = 9.  This is correct.
