The volume (in cubic meters), v, of a rectangular room is given by the expression:
v = 7b^4-28
where b is a positive integer and each dimension is a positive integer too. what are three unique expressions that could represent the dimensions of the room?
write these three expressions as a product that equals the volume (e. g. "(expression 1)(expression 2)(expression 3)").

  7(b^2 -2)(b^2 +2)

Step-by-step explanation:

Factoring the common factor 7 from both terms, you get the difference of squares. That can also be factored.

  v = 7(b^4 -4) = 7(b^2 -2)(b^2 +2)

The difference b^2-2 will have irrational factors, so does not meet the problem requirements. This is the factorization over integers.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
