- 9(2x + 1) - 2(3 - x) =
- 18x + 9 - 6 + 2x =
- 20x + 3
Step-by-step explanation:
f(x) = | x² - x + 3 |
f(-1) = |(-1)² - (-1) + 3| = |1 + 1 + 3| = |5| = 5
f(5) = |(5)² - (5) + 3| = |25 - 5 + 3| = |23| = 23
f(-10) = |(-10)² - (10) + 3| = |100 - 10 + 3| = |93| = 93

circumference is actually a closed boundary of a curved geometric figure like circle.
it can be calculated by applying the formula C = π * d ( d= diameter)
or C = 2πr ( r= radius)
you can use any one to find out the circumference of the circle.
But from your attached document,it is clear that circumference is given, sorry, I don't understand for what you are looking for?
diameter goes straight through the center of a circle and touches the boundaries of the circle in both sides.
Diameter is always double of radius, D = 2r ( r= radius)
or you can find radius by dividing it by 2,
r = D/2
I hope it will serve your purpose.
Answer:
- 4 < x < 2
Step-by-step explanation:
Given
- 1 < x + 3 < 5 ( subtract 3 from each interval )
- 1 - 3 < x + 3 - 3 < 5 - 3 , that is
- 4 < x < 2
