2) -8(-8x - 6) = -6x – 22
Answers
Answer:
x = -1
Step-by-step explanation:
-8(-8x - 6) = -6x - 22 {Use distributive property}
(-8) * (-8x) - 6 *(-8) = -6x - 22
64x + 48 = -6x -22 {Add 6x to both sides}
64x + 6x + 48 = -22 {Subtract 48 from both sides}
70x = -22 -48
70x = -70 {Divide both sides by 70}
x = -70/70
x = -1

Answer:
To find the circumference, you multiply the radius by 2 and then multiply that by pi (or π). The equation is 2πr
In this case, we already have the radius x 2, which is the diameter. For this circle, the diameter is 12 cm.
The next step is to multiply the diameter, 12 cm, by pi (π is about equal to 3.14)
12 x π ≈ 37.698 cm or 38 cm rounded to the nearest whole number
