Please help on the Line Plot one! ASAP! Please
tamaranim1 [39]
Draw a straight, horizontal line.  Mark evenly-spaced scale divisions, 0 to 5 (because all of the given numerals fit within this domain).

Recognize that the LCD of these fractions and mixed numbers is 6.

Convert all of the given fractions to denominator 6, as needed (some already have that denominator).

Arrange the resulting fractions in ascending order.  For example, 5/6, 1/6, 3/6 would become 1/6, 3/6, 5/6 (in ascending order).

Plot all your numerals (all of which have denominator 6) on your number line.

The area of a rectangle is expressed as x4 - 9y2. What are the possible dimensions of the rectangle?
AnnyKZ [126]

This is a stupid question.  The teacher who asked this needs to go back to school.

A = x⁴ - 9y²

That's going to be a number.  As long as it's positive we can choose any length for our rectangle L and we can compute the width by W=A/L.   So the correct answer is the dimensions are L by  (x⁴ - 9y²)/L.

They don't want the correct answer.  They want you to factor this expression.  We'll do it, but don't believe for a second this factoring somehow constrains the possible dimensions of some rectangle.

We use the difference of two squares, a²-b² = (a+b)(a-b)

A = x⁴ - 9y² = (x²)² - (3y)² = (x²+3y)(x²-3y)

Answer: x²+3y  by  x²-3y
