the length of a rectangle is 5 less than twice the width. If the perimeter of the rectangle is 146 centimeters, find the dimensi

d1i1m1o1n [39]

Answer:

26x47

Step-by-step explanation:

To calculate the length of the rectangle we would do 2(2x - 5) + 2(x) = 146

We simplify and get 6x - 10 = 146,

then divide both side by 6 and plus 10 both sides,

we will get

x = 26

Now we've found one of the length,

to find the other side we do 26 * 2 = 52, and subtract 52 from 146,

which would get 94, then we divide it by 2

94/2 = 47

The dimensions is 26x47

What is the value of xy over z if x =-2 y=-3 and z=4

Art [367]

$\dfrac{xy}{z};\ x=-2,\ y=-3,\ z=4$

Substitute the values of x, y and z to the expression:

$\dfrac{(-2)(-3)}{4}=\dfrac{6}{4}=\dfrac{6:2}{4:2}=\dfrac{3}{2}$

Does anyone know how to answer this question? Please write your working calculation as well if you do know the answer. Thanks so

krek1111 [17]

Answer:

Mark as brainliest if helped Thanks!

Step-by-step explanation:

funtion is:

$y = \frac{x^2 -1}{2x + 1}$

therefore $\\\frac{dy}{dx}\\$ is

$\frac{d\frac{x^2 -1}{2x + 1}}{dx}$

$\frac{\frac{x^2 -1}{2x + 1}}{x}$

$\frac{x^2 -1}{(2x+1) x}$

Now

$\int\limits^2_0 {\frac{x^2 +x +1 }{4x^2 +4 + 1} } \, dx$

(Calculation of this it too long and it is hard to type on brainly)

here is the answer though....

= 4/5
