The answer to this question would be 4.42 so 4
Multiply it out.
f(x) = (2x +1)(x² -1) . . . . . . recognize the factoring of the difference of squares
f(x) = 2x³ +x² -2x -1
Answer:
This statement is false. The side of a triangle that is opposite an angle greater than or equal to 90° is always the largest side of the triangle.
Assuming the vertex of the triangle shown is the center of the pentagon, and the line segment shown is an altitude of the triangle:
If we join the center of (the circumscribed circle and of) the pentagon to the 5 vertices, 5 isosceles triangles are formed, all congruent to the one shown in the figure. It is clear that these triangles are congruent, so to find the area of the pentagon, we find the area of one of these triangles and multiply by 5.
The base of the triangle is 22.3 in, and the height is 15.4 ins, thus the area of the pentagon is:
5(Area triangle)=5*[(22.3*15.4)/2]=<span>858.55 (square inches).
Answer: </span>858.55 (square inches).
