Answer:

$\frac{1}{2x}$ , x ≠ 0

Step-by-step explanation:

Given

$\frac{2x-5}{4x^2-10x}$ ← factor the denominator by factoring out 2x from each term

= $\frac{2x-5}{2x(2x-5)}$ ← cancel the factor (2x - 5) on numerator/ denominator

= $\frac{1}{2x}$

The denominator cannot be zero as this would make it undefined.

Thus x = 0 is the non- permissible value

Find the length of the leg x. enter the exact value, not a decimal approximation x1210x=

zzz [600]

We can solve for the value of x using pythagorean theorem

$c^2=a^2+b^2$

where c is the hypotenuse ( in this case is 15) and a, b are the other legs of the triangle ( in this case is 8 and x).

Let's substitute the given values to the formula

$\begin{gathered} c^2=a^2+b^2 \\ 15^2=8^2+x^2 \\ 225=64+x^2 \\ x^2=225-64 \\ x^2=161 \\ x=12.69 \end{gathered}$

Now please follow this solution to solve for x in:

The perimeter of a rectangle is 38 units. The length is 13 units longer than the width. What are the dimensions of the rectangle

s2008m [1.1K]

Answer:

Step-by-step explanation:

P = 2(l +w)

Let width be x

Length = x + 13

P = 38

38 = 2(x + 13 + x)

38 = 2(2x + 13)

38 = 2x + 26

2x = 38 - 26

2x = 12

x = 12/2

x = 6unit

Width = 6units

Length = x + 13 = 6+13 = 19units
