What are the steps for this equation?

Answer and Step-by-step explanation:

Essentially, what we want to do is isolate the variable, which is x in this case. In order to do so, we need to "undo" all the operations on the left to separate x.

Our equation is:

2(x + 2)² - 5 = 93

To "undo" the subtract 5, add 5 to both sides:

2(x + 2)² = 93 + 5 = 98

To "undo" the multiply by 2, divide by 2 from both sides:

(x + 2)² = 98/2 = 49

To "undo" the square, square root both sides:

x + 2 = √49 = ±7

TO "undo" the plus 2, subtract 2 from both sides:

x = ±7 - 2

And our final answers are 5 and -9.

The steps are thus:

- Add 5 to both sides

- Divide both sides by 2

- Take the square root of both sides

- Subtract 2 from both sides

Step-by-step explanation:

Step 1:  Add 5 to both sides

Step 2:  Divide both sides by 2

Step 3:  Take the square root of both sides

Step 4:  Subtract 2 from both sides

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
