If you would like to solve for the positive value of x, you can do this using the following steps:

6 * x^2 - 54 = 0      /6
x^2 - 9 = 0
(x - 3) * (x + 3) = 0
1. x = 3
2. x = - 3

The correct result would be x = 3.

Answer: 36.84

(lmk if this isnt right)

Step-by-step explanation:

To find the perimeter of the rectangle:

3+3+3+3+3+3=18

or

3(6)=18

To find the diameter of the circle:

12-(3+3)

12-6=6

You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.

C=πd

Substitute

C=3.14(6)

Multiply

C=18.84

Add the perimeter of the rectangle and the circumference of the circle.

18+18.84=36.84

Step-by-step explanation:

A 2-column table with 3 rows. Column 1 is labeled x with entries 16, 32, 48. Column 2 is labeled y with entries 1, 2, 4.

No, as x= 4 ⇒ y =64 not 48

A 2-column table with 3 rows. Column 1 is labeled x with entries 1, 5, 6. Column 2 is labeled y with entries 5, 20, 30.

No, as x = 5 ⇒ y = 25 not 20

A 2-column table with 3 rows. Column 1 is labeled x with entries 14, 28, 42. Column 2 is labeled y with entries 2, 4, 6.

Yes, as 2*7 = 14, 4*7= 28, 6*7= 42

A 2-column table with 3 rows. Column 1 is labeled x with entries 0, 1, 3. Column 2 is labeled y with entries 25, 70, 90.

No, x = 3 ⇒ y= 25+3*45= 160 not 90
