Answer:

z = -35

Step-by-step explanation:

2/7z = -10......divide both sides by 7/2

7/2(2/7)z = (-10)7/2

z = -70/2

z = -35

Factorization of the given polynomial to find the product is as follows;

Factorizing;

\dfrac{x^2 + 3*x +2}{x^2+ 6*x + 5} = \dfrac{(x + 1) * (x + 2)}{(x + 1)*(x + 5)}

\dfrac{x^2 + 7*x +10}{x^2+ 4*x + 4} = \dfrac{(x + 2) * (x + 5)}{(x + 2)*(x + 2)}

Expressing the product in terms of the factors

\dfrac{x^2 + 3*x +2}{x^2+ 6*x + 5} \times  \dfrac{x^2 + 7*x +10}{x^2+ 4*x + 4} = \dfrac{(x + 2) * (x + 5)}{(x + 2)*(x + 2)} \times \dfrac{(x + 1) * (x + 2)}{(x + 1)*(x + 5)}

The steps arranged in the order in which they would be performed are;

First step;

\dfrac{x^2 + 3*x +2}{x^2+ 6*x + 5} \times  \dfrac{x^2 + 7*x +10}{x^2+ 4*x + 4}

↓

Second step (factorizing)

\dfrac{(x + 2) * (x + 5)}{(x + 2)*(x + 2)} \times \dfrac{(x + 1) * (x + 2)}{(x + 1)*(x + 5)}

↓

Third step (dividing out common terms)

\dfrac{(x + 5)}{(x + 2)} \times \dfrac{(x + 2)}{(x + 5)}

↓

Fourth step (rearranging and removing terms that cancel each other)

The area of a rectangle is 348 square inches. the width is 6 inches. what is the length
Aleks04 [339]
In order to find the length of the rectangle, we have to use the area formula for a rectangle. Then, we can substitute the values we've been given and use basic algebra to find the answer.

A = lw   Area of a rectangle
348 = 6l   Substitute
58 = l   Divide both sides by 6 

The length of the rectangle is 58 inches.

4. Nguyen is decorating the room for her sister's baby shower party. She is wrapping
Marianna [84]

Answer:

Step-by-step explanation:

Given the information of the conical hat

  • diameter of 16 inches => Radius = 8 inches
  • height of 9 inches

=> the slant height of the hat is (use Pythagorean Theorem)

s^{2} = r^{2} + h^{2}

<=> s^{2} = 8^{2} + 9^{2}

<=> s = \sqrt{145}  

The area (without the base area) of tissue paper will she need to make one hat is:

SA = πrs  in2

<=> SA =  π*8*\sqrt{145}  in2

<=> SA =8 \sqrt{145} π

=> the total tissue paper will she need for 21 hats is:

SA*21

= 8 \sqrt{145} π*21

= 6352,18 in 2
