1) What is the GCF for the polynomial 4x3 - 2x2y?2) What is the GCF for the polynomial 8x4y + 6x2y2?

3) What is the GCF for the polynomial 12x3y2 - 20x5y3?

4) What is the GCF for the polynomial -10x3y4 - 16x5y2?

Answers

(1)the GCF for the polynomial $4x^3 - 2x^2y$

4x^3 = 2*2* x* x* x

2x^2y = 2*x*x*y

Greatest common factor is $2*x*x = 2x^2$

(2) the GCF for the polynomial $8x^4y + 6x^2y^2$

$8x^4y = 2*2*2*x*x*x*x*y$

$6x^2y^2 = 3*2*x*x*y*y$

GCF is $2*x*x*y=2x^2y$

(3) the GCF for the polynomial $12x^3y^2 - 20x^5y^3$

$12x^3y^2 = 2*2*3*x*x*x*y*y$

$20x^5y^3=5*2*2*x*x*x*x*x*y*y*y$

GCF is $2*2*x*x*x*y*y= 4x^3y^2$

(4) the GCF for the polynomial $-10x^3y^4 - 16x^5y^2$

$-10x^3y^4 =-2*5*x*x*x*y*y*y*y$

$-16x^5y^2=-2*2*2*2*x*x*x*x*x*y*y$

GCF is $-2*x*x*x*y*y= -2x^3y^2$

Answer:

1. 2x2

2. 2x2y

3. 4x3y2

4. -2x3y2

Step-by-step explanation:

1. 4x3 - 2x2y= GCF: 2x2

2. 8x4y + 6x2y2= GCF: 2x2y

3. 12x3y2 - 20x5y3= GCF: 4x3y2

4. -10x3y4 - 16x5y2= GCF: -2x3y2

      (x² - y²)² + (2xy)² = (x² + y²)²
   (x² - y²)(x² - y²) + 2x²y² = (x² + y²)(x² + y²)
      x²(x² - y²) - y²(x² - y²) + 2x²y² = x²(x² + y²) + y²(x² + y²)
x²(x²) - x²(y²) - y²(x²) + y²(y²) + 2x²y² = x²(x²) + x²(y²) + y²(x²) + y²(y²)
      x⁴ - x²y² - x²y² + y⁴ + 2x²y² = x⁴ + x²y² + x²y² + y⁴
         x⁴ - 2x²y² + y⁴ + 2x²y² = x⁴ + 2x²y² + y⁴
   x⁴ - 2x²y² + 2x²y² + y⁴ = x⁴ + 2x²y² + y⁴
      x⁴ + y⁴ = x⁴ + 2x²y² + y⁴
      - x⁴    - x⁴
   y⁴ = 2x²y² + y⁴
       - y⁴ - y⁴
      0 = 2x²y²
      2    2
      0 = x²y²
      0 = xy

Find the slope of the line that contains the points named. K(c + d, c - d), L(c - d, c + d)
a. -1
b. 1
c. 0

Answers

Answer:

Option A is correct .i.e., Slope is -1.

Step-by-step explanation:

Given points are K(c+d , c-d) & L(c-d , c+d)

$Slope\:of\:line=(y_2-y_1)/(x_2-x_1)$

$Slope\:of\:line\:KL=(c+d-(c-d))/(c-d-(c+d))$

$=(c+d-c+d)/(c-d-c-d)$

$=(2d)/(-2d)$

$=-1$

Therefore, Option A is correct .i.e., Slope is -1.

Hello,

Answer A

slope= (c+d-(c-d))/(c-d-(c+d))=2d/(-2d)=-1

the sales tax for a certain state can ne found ny multiplying the purchase price by 1/20 what is the sales.tax on an item that is 25.60 express your answer as a decimal

Answers

The salestax on an item that is 25.60 dollars is 1.325 dollars.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

There are two types of fractions one is a proper fraction and another one is an improper fraction.

In proper fractions, the numerator is smaller than the denominator and in improper fractions, the numerator is greater than the denominator.

Given, sales tax for a certain state can be found by multiplying the purchase price by 1/20.

∴ Sales tax on an item that is 25.60 is 25.60×1/20.

= 1.325 dollars.

First, convert 1/20 to decimal form:
1/20 = 0.05
This means that the sales tax rate is 5%.
Multiply the cost of the item times 0.05 to get the amount of the sales tax:
25.60 * 0.05 = $1.28 sales tax
