Which polynomial is factored completely
Ket [755]

Answer: The correct option is c.

Explanation:

Reason for correct option:

3x(9x^2+1)

This expression cannot be factored further because (9x^2+1) is the complete factor. Therefore the option c is correct.

Reason for incorrect option:

5x^2-17x+14=5x^2-10x-7x+14=5x(x-2)-7(x-2)=(x-2)(5x-7)

Since the given expression can be factored further therefore the option d is incorrect.

4(4x^4-1)=4((2x)^2-1)=4(2x^2-1)(2x^2+1)

Since the given expression can be factored further. Therefore the option a is incorrect.

2x(y^3-4y^2+5y)=2xy(y^2-4y+5)

Since the given expression can be factored further. Therefore the option b is incorrect.

pogonyaev
The ramp will form a triangle with height 2ft and base 6ft.

The length of the ramp will be the hypotenuse of this triangle.
length² = height² + base²
length = √(height² + base²)
length = √(2² + 6²)
length = √(4 + 36)
length = √40
length = 6.3ft

Therefore, the ramp will be 6.3ft long.
