2x = 1/2

divide each side by 2

2x /2 = 1/2 /2

x = 1/4

x=1/4 or .25 , because 1/2 divided by 2 is 1/4.

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).

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
