2x 6=28
Write the Value of x

Answers

Answer 1
Answer:

Answer:

11

Step-by-step explanation:

2*11=22

22+6=28=28

so it is equal it means that x value is eleven
Answer 2
Answer: The answer is 11 because since you are trying to find the value of x you would have to isolate x. The way you would is bring 6 to the other side with 28 because what ever you do to one side you have to do the other side. So, 28 - 6 = 22.

2x = 22
Now you can divide 2 by 2 and 22 by 2 so x is alone. 22/2 = 11 and that is the value of x.

Figure 2 length 10 width find perimeter and area

Answers

Alrighty man, I'm gonna teach you a math.
If you're looking for perimeter, thats how long the shape is on the outside. To find the perimeter, add your base and your height and multiply it by two. For us, height is 10, and base is 2. 10+2x2= 24.
To find area, you have to multiply the base times the height. 10x2= 20
The area is 20 units squared and the perimeter is 24 units.

Simplify the expression 3x(x-12x)+3x^2-2(x-2)^2.which statements Are true about the process and simplified product check all that apply

Answers

Answer:

-8 (4 x^2 - x + 1)

Step-by-step explanation:

Simplify the following:

3 x (x - 12 x) + 3 x^2 - 2 (x - 2)^2

x - 12 x = -11 x:

3 x×-11 x + 3 x^2 - 2 (x - 2)^2

3 x (-11) x = 3 x^2 (-11):

-11×3 x^2 + 3 x^2 - 2 (x - 2)^2

3 (-11) = -33:

-33 x^2 + 3 x^2 - 2 (x - 2)^2

3 x^2 - 33 x^2 = -30 x^2:

-30 x^2 - 2 (x - 2)^2

(x - 2) (x - 2) = (x) (x) + (x) (-2) + (-2) (x) + (-2) (-2) = x^2 - 2 x - 2 x + 4 = x^2 - 4 x + 4:

-30 x^2 - 2 x^2 - 4 x + 4

-2 (x^2 - 4 x + 4) = -2 x^2 + 8 x - 8:

-2 x^2 + 8 x - 8 - 30 x^2

Grouping like terms, -2 x^2 - 30 x^2 + 8 x - 8 = (-30 x^2 - 2 x^2) + 8 x - 8:

(-30 x^2 - 2 x^2) + 8 x - 8

-30 x^2 - 2 x^2 = -32 x^2:

-32 x^2 + 8 x - 8

Factor -8 out of -32 x^2 + 8 x - 8:

Answer:  -8 (4 x^2 - x + 1)

A hardcover book sells for $24 at the bookmart. Ben pays a total of $25.02 for the book. What is the sales tax rate?

Answers

Increase in price = $25.02 - $24.00
                   
                         = $1.02

Tax rate = (1.02)/(24.00)

Tax rate = 0.0425

0.0425 = 4.25%

She found that each store’s charge for the job could be modeled by a linear function that combined a flat charge for artwork with a per T-shirt rate.

How should Marissa interpret this result?A.Those two vendors charge the same rate per shirt.B.Those two vendors charge the same flat rate for artwork.C.Those two vendors will have the same total cost to produce one shirt.D.Those two vendors will charge the same total cost for any size job.
