Which binomials below is a factor of this trinomial 5x^2-5x-100
34kurt
We are asked to determine the correct factorization of the given trinomial which is 5x² - 5x -100. The solution to this problem is shown below:
5x² - 5x - 100 let the problem equal to zero such as:
5x² - 5x - 100 = 0 , factor out 5 from the given trinomial
5(x²-x-20) = 0
5 (x-5)(x+4) = 0

The correct factor is 5(x-5)(x+4).

Complete Question

The diagram for this question is shown on the first uploaded image

Answer:

The value of x is  x = 274 \ unites

Step-by-step explanation:

From the question we are told that

       The length of the vertical length is  x

      The length of the base leg is L = 330 + d units

      The length of the bisecting line segment is h

       The base angle is \theta  = 28^o

       The angle between d and line segment is  \theta_1 =  56^o

For the first angle

         Tan \theta_1 =  \frac{x}{d}

=>     d =  \frac{x}{Tan \theta _1}

 For the whole big triangle

      Tan \theta = \frac{x}{330 + d}

=>     d = \frac{x}{Tan \theta }  -330

So equating the both d

        \frac{x}{Tan \theta _1} =    \frac{x}{Tan \theta }  -330

Substitute values

        \frac{x}{Tan (56)} =    \frac{x}{Tan (28) }  -330

      0.6745 x =    1.880x  -330

       1.20549 x = 330

       x = 274 \ unites

An expression involves subtracting two numbers from a given first number under what circumstance will the value of the expressio
vagabundo [1.1K]

Say that you start from a number x. Then, you subtract y and z from x, which means that the expression is

x-y-z = x-(y+z)

If we want this expression to be negative, we have

x-(y+z)

So, in order for the expression to be negative, the two numbers we are subtracting, combined, must be more than the starting number.

For example, if we start from 10 and we subtract 4 and then 8, we have

10-4-8 = 10-12=-2

which is negative, because 4 and 8 combined are more than 10
