Area of quilt, Q= $60^2\, in^2=3600\,in^2$
Area of purple square, P = $(x-5)^2\, in^2$
Area of white area
= Q-P
= $3600-(x-5)^2\, in^2$
= $3600-x^2+10x-25\, in^2$
= $3575-x^2+10x\, in^2$

Maria cut 3/4 yard of ribbon into pieces that are 1/8 yard long. How many pieces of ribbon did Maria cut? don't be a b.*.t.c.h.

Akimi4 [234]

<h3>Answer: 6 pieces</h3>

===============================================

Explanation:

3/4 = 6/8 after multiplying top and bottom of the fraction by 2

She has 6/8 of a yard of ribbon.

If she cuts the ribbon into pieces of 1/8 of a yard each, then she has 6 pieces overall

We can see this if we solve the equation (1/8)x = 6/8. Multiply both sides by 8 to get x = 6.

A= x^2 -30x+225 The polynomial represents the area (in square feet) of the square playground. a. Write a polynomial that represe

Setler [38]

Answer:

a) The polynomial is equivalent to $A = (x-15)^{2}$ , and the side length of the playground is $x -15$ feet.

b) The perimeter of the playground, measured in feet, is $p = 4\cdot (x-15)$ .

Step-by-step explanation:

a) By Geometry, we know that area of the square is equal to the square of the side length. If $A = x^{2}-30\cdot x +225$ is the area of the square, then must be a perfect square trinomial, that is:
