Answer:
2x³-3x²+4
Step-by-step explanation:
F(x) = 2x-1
g(x)=x²-2
g.f(x) = (x²-2)(2x-1)
open the bracket
x²(2x-1)-2(x²-2)
2x³-x²-2x²+4
2x³-3x²+4
Answer:
Question 1: 3. certain
Question 2: 2. 1/6
Step-by-step explanation:
There are six sides on a die.
1. You cannot roll a 7.
2. You can roll a 1, there is a 1/6 chance you roll that. However, there is zero chance you roll an 8.
The sum of the exterior angles of a pentagon is 360 degree
Answer:
uh yea
Step-by-step explanation:
"An angle that forms a linear pair with one of the interior angle the triangle" is the best definition of an exterior angle of a triangle.
<u>Option: C</u>
<u>Explanation:</u>
When to the sum of the inward angles opposite outer angle of a triangle the sum of the inward angles opposite is equivalent thus understood as exterior angle of a triangle.
The Triangle outer angle theorem for more about is if at each vertex the equivalent angle is drawn, the outer angles always add up to 360°. In reality, this is valid for any convex polygon, not just triangles.
In the most easiest pattern , since any angle of triangle equivalent is 60′, the outer angle would be 120′. Therefore all exterior angles sum is:
120 + 120 + 120 = 360°.
