Which of the binomials below is a factor of this trinomial? x^2 + 3x - 4A. x+4B. x+8C. x-4D. x^2+4

Usimov [2.4K]

Given:

The equation is:

$x^2+3x-4$

Find-:

Binomials factor of the equation

Explanation-:

The quadratic equation,

$x^2+3x-4$

Solve for factor

$\begin{gathered} =x^2+3x-4 \\ \\ =x^2+4x-x-4 \\ \end{gathered}$

Then the factor is:

$\begin{gathered} =x^2+4x-x-4 \\ \\ =x(x+4)-1(x+4) \\ \\ =(x+4)(x-1) \end{gathered}$

So, the factor is x + 4

For the values a=8 which is a leg of a right triangle and value c=19 which is the hypotenuse find the length of the other leg b

FinnZ [79.3K]

C^2=a^2+b^2 we are given the hypotenuse of 19 units and one leg of 8 units so:

19^2=8^2+b^2

361=64+b^2

b^2=297

b=√297

b≈17.2 to the nearest tenth
