Answer:

B. (9x - 5y)(9x + 5y)

Step-by-step explanation:

when you are factoring these, when you have a negative and a positive, there is a number that will cancel. in this case, when distributing the factors, the number 45xy and -45xy come up. those cancel.

Answer:

The Answer is 12 - 15= 129

Step-by-step explanation:

x2−15=129

Step 1: Add 15 to both sides.

x2−15+15=129+15

x2=144

Step 2: Take square root.

x=±√144

x=12

Answer:

D

Step-by-step explanation:

(4.5+3+2) x4.5 = 42.75

hope this helps

Answer:

D. 42.75 square inches

Step-by-step explanation:

Area = height x width

Height = 4.5 inches

Width = 3 + 4.5 + 2 = 9.5 inches

4.5 x 9.5 = 42.75 square inches

Answer:

4/6

Step-by-step explanation:

Make 1/3 into 6 as its denominator.

1 x 2 = 2

3 x 2 = 6

Step-by-step explanation:

Answer: C.) If the sum of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle.

Step-by-step explanation: i hope this helps! :)

The correct statement is (C)

The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The Pythagoras theorem equation is expressed as, c2 = a2 + b2, where 'c' = hypotenuse of the right triangle and 'a' and 'b' are the other two legs. Hence, any triangle with one angle equal to 90 degrees produces a Pythagoras triangle and the Pythagoras equation can be applied in the triangle.

example:

The hypotenuse of a right-angled triangle is 16 units and one of the sides of the triangle is 8 units. Find the measure of the third side using the Pythagoras theorem formula.

Given : Hypotenuse = 16 units

Let us consider the given side of a triangle as the perpendicular height = 8 units

On substituting the given dimensions to the Pythagoras theorem formula

Hypotenuse2 = Base2 + Height2

162 = B2 + 82

B2 = 256 - 64

B = √192 = 13.856 units

So, Using the definition of Pythagoras theorem

the statement would be

If the sum of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle.

Answer:

D) 18a

Step-by-step explanation:

y - x

= 4x - x (plug y = 4x)

= 3x

= 3(2z) (plug x = 2z)

= 6z

= 6(3a) (plug z = 3a)

= 18a

Answer:

(-20, 0)

Step-by-step explanation:

to find x intercept we have to substitute 0 into y and solve for x

0 = -x - 20

rewriting the equation

-x - 20= 0

-x = 20

Answer:

x = 16

Step-by-step explanation:

Supplementary angles = 180

K + L = 180

137 + 3x - 5 = 180

132 + 3x = 180

3x = 180 - 132

3x = 48

x = 48/3

x = 16

Answer:

x intercept is (33,0)

y intercept is (0, 11)

Step-by-step explanation:

x-intercepts are found when y=0

x + 3(0)=33,,, x=33

y-intercepts are found when x=0

0 + 3y= 33,,, y=11

Step-by-step explanation:

Answer:

1. 53 97 159

2 6 and 6.1

3. 1 1/3

Answer:

The Identity Property of Zero, also called the Additive Identity Property, states that if you add 0 to any number, the result will be that number. Likewise, if you subtract 0 from any number, the result will be that number. Believe it or not, this works for all real numbers.

Step-by-step explanation:

Answer:

In Java:

import java.util.Random;

public class Main{

public static void main(String args []){

  int Employee;

  for(int weeks = 1;weeks<=52;weeks++){

    Employee = 1 + (int)(Math.random() * 30);

    System.out.println("Week "+weeks+" selected employee: "+Employee);

  }

}

}

Step-by-step explanation:

This imports the Random package into the program

import java.util.Random;

public class Main{

public static void main(String args []){

Declare employee as integer (represents employee 1 to 30)

  int Employee;

Iterate from week 1 to 52

  for(int weeks = 1;weeks<=52;weeks++){

Randomly select an employee from 1 to 30 (inclusive)

    Employee = 1 + (int)(Math.random() * 30);

Print the selected employee

    System.out.println("Week "+weeks+" selected employee: "+Employee);

  }

}

}

Answer:

The unit rate is $1.99. The price of eight pounds of strawberry $15.92.

Step-by-step explanation:

To find the unit price, you divide $11.94 by 6 and you get $1.99. For eight pounds, multiply $1.99 with 8 and you get $15.92.

Answer:

$15.92

Step-by-step explanation:

First find the price of one pound. 11.94÷6=1.99 Once you find the price of 1 pound. You multiply the price of one pound 8 times. 1.99×8=15.92 Hope it helps!
