When y intercpets, x = 0
so here,
ƒ(x)=x^3-x^2-x+1
ƒ(x)=(0)^3-(0)^2-0+1
ƒ(x)= +1
The area of a triangle is the amount of space on the triangle
The expression that represents the area of the triangle is 
The coordinates of the triangle are given as:



The area (A) of a triangle from its coordinates or vertices are:

Substitute values for x's and y's

Hence, the expression that represents the area of the triangle is

Answer:
The least common multiple would be 105.
Step-by-step explanation:
You would do list out the multiples for each. Or multiply
Since 3 x 30 is 90, and 3 x 5 is 15, This is 105
And since 5 x 20 is 100, and 5 x 1 is 5, This is 105 as well
Also, since 7 x 10 is 70, and 7 x 5 is 35, This is 105.
The LCM is 105
Have a great Day!
Well umm check calculator again maybe you did a mistake in typing one of the numbers
D
using the double - angle identity
cos (2A) = cos² A - sin² A = 2cos² A - 1 = 1 - 2sin² A
the right side = 1 - 2sin² (112.5° ) with A = 22.5°
hence 2A = 2 × 22.5° = 45°
thus cos 45° = 1 - 2sin² ( 22.5°)
