The swimming pool at Spring Valley High School is a rectangle with a width of `30` meters and a length of `24` meters. The principal wants to add a walkway around the perimeter of the pool is a tiled floor that extends `y` meters from the pool on all sides. Write an expression for the combined area of the walkway and pool as a product of two binomials. Simplify the expression in standard form. Provide the algebraic justification in the space provided below.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a, b and c integers and a> 1

Ingredient c: 1/4 cup for 2/3 serving or ingredient d: 1/3 cup for 3/4 serving which unit rate is smaller
