Evaluate the expression x+4x-3+3x^2-2x when x = 5

Given:

The expression is

To find:

The value of given expression when x=5.

Solution:

We have,

Substituting x=5 in the above expression, we get

On further simplification, we get

Therefore, values of the given expression at x=5 is 87.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
