2x^2 +5x+3/x^2+2x+1

german

Answer:

$\frac{2x+3}{x+1}$

Step-by-step explanation:

2x² + 5x + 3 = (x + 1) (2x + 3)

x² + 2x + 1 = (x + 1) (x + 1)

(x + 1) cancels out because there is one in the denominator and the numerator, leaving you with the answer.

The equation (x-7)^2 + (y - 6)^2 = 36 represents a Ferris wheel plan displayed on a grid, where each unit represents 1 meter. Wh

lys-0071 [83]

Answer:

$12m$

Step-by-step explanation:

we are given a circle equation

$\displaystyle (x - 7 {)}^{2} + (y - 6 {)}^{2} = 36$

since it's a circle equation where 36 is the square of the redious we can figure out redious by solving the following equation

$\displaystyle {r}^{2} = 36$

square root both sides:

$\displaystyle {r}^{} = 6$

remember that,

$\displaystyle d = 2r$

thus substitute the value of r:

$\displaystyle d = 2.6$

simplify multiplication:

$\displaystyle d = 12$

hence,

the diameter of the Ferris Wheel is 12m
