Solve for x: 3|2x − 2| + 6 = 18.
x = 3, x = −3
x = 3, x = −1
x = 1, x = −1
x = −3, x = 1

Option 2 - x = 3, x = −1

Step-by-step explanation:

Given : Expression

To find : Solve the expression ?

Solution :

The expression gives an absolute function which means

Expression

1) Taking

Solving,

2) Taking

Solving,

Therefore, The solution of  is x=3,-1.

So, Option 2 is correct.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
