There are 25 desks in mr. miller’s class. there are 36 desks in mrs. fernandez’s class. the desks in each classroom are arranged in a square. the equation n2=25 can be used to find how many desks are in each row in mr. miller’s class. the equation n2=36 can be used to find how many desks are in each row in mrs. fernandez’s class. how many desks are in each row in each class.

Assuming the equations are supposed to read =25 , you can find the square root of both sides to find n.

The square root of 36 is 6, and the square root of 25 is 5.

n=5 and n=6

So, in Mr. Miller's class, there are 5 desks in each row.

In Mrs. Fernandez's class, there are 6 desks in each row.

Hope this helps :)

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
