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

3) 756/100 * 42 = 317.52 = 320
4) 460/100 * 11 = 50.6

Answer:

6 m

Step-by-step explanation:

a squared + b squared = c squared

8 squared plus ? squared = 10 squared

64 + ? = 100

100 - 64 = 36

the square root of 36 is 6

<h2><u>Functions</u></h2>

The relationship between both prices is determined by function (R - 1 = B + 2).

It is clear that for each pound less of brown rice there will be 2 more pounds of beans, with which there is a direct relationship between both quantities, which is determined through a function (R - 1 = B + 2).

Given that brown rice cost $ 2 per pound, and beans cost $ 1 per pound, and Alexa has $ 10 to spend on these items to make a meal for a dinner she is attending, to determine if it is the amount of rice purchased a function of the amount of beans purchased, the following calculation must be performed:

  • 2 x 5 + 0 = 10
  • 2 x 4 + 2 = 10
  • 2 x 3 + 4 = 10
  • 2 x 2 + 6 = 10
  • 2 x 1 + 8 = 10
  • 2 x 0 + 10 = 10

Therefore, it is clear that for each pound less of brown rice there will be 2 more pounds of beans, with which there is a direct relationship between both quantities, which is determined through a function (R - 1 = B + 2).
