The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.A table with 6 columns and 2 rows. The first column, Original System has 2 x minus 2 y equals 6 and 4 x plus 4 y equals 28. The second column, Equivalent System, has 4 x minus 4 y equals 12 and 4 x plus 4 y equals 28. The third column, Sum of equations in Equivalent System, has 8 x equals 40. The fourth column, Solution to System, is blank. The fifth column, New System Using Sum, has 4 x plus 4 y equals 28 and 8 x equals 40. The sixth column, Solution to New System is blank.

Which solution can be used to fill in both blanks in the table?

(2, 5)

(5, 2)
(5, −8)
(−8, 5)

Answers

Answer:

(5,2)

Step-by-step explanation:

2x-2y=6\n4x+4y=28

Column 1 :

2x-2y=6..........(1)\n4x+4y=28........(2)

Column 2 :

Eqn(1) *\ 2

4x-4y=12\n4x+4y=28

Column 3 :

Add the equations.

(4x+4x)-4y+4y=12+28\n8x=40

Fourth column :

8x=40\nx=(40)/(8)=5

Fift column :

4x+4y=28\n8x=40

Sixth column :

Substitute x=5.

4* 5+4y=28\n4y=28-20\n4y=8\ny=2

Hence solution is (5,2).

To make this problem easy let's change fraction to  decimal.
So, our width is (3)/(2) = 1.5

Area of rectangular prism = l * w * h
                                             = 11 * 1.5 * 4
                                             = 66 inch³
Answer = 66 inch³

Hope this helps you  :)

The length of consecutive sides of a rectangle are represented by 2x+1 and 3x+2.Express the area of the rectangle in terms of x

Answers

Hello AnneBunny!

The area of a rectangle is the base multiplied by its height.

The answer is  6x^2+7x+2

Thus, (2x+1)(3x+2) is equal to 6x^2+7x+2

(3-2x) divided by (1 divided by x+5) multiplied by 8

Answers

Answer: 8(3-2x)(x+5), -16x^2-56+120, x=-5, or x=3/2.


Step-by-step explanation:

First convert the multi fraction into multiplication: 8(3-2x)(x+5)

Then simplify: -16x^2-56+120

If you want, you can solve for x, which gets you x=-5, or x=3/2.

I hope this helps! :P
