El área de la región rectangular es 4400cm2. Calcula el valor de m

Roman55 [17]

Answer:

m=52.17

Step-by-step explanation:

<em>The complete question in Spanish is</em>

El área de la región rectangular es 4400 cm2. Calcular el valor de m

largo :2m-20

ancho: m

<em>The question in English is</em>

The area of the rectangular region is 4400 cm2. Calculate the value of m

length :2m-20

width: m

we know that

The area of a rectangle is equal to

$A=LW$

where

L is the length

W is the width

we have

$A=4,400\ cm^2$

$L=(2m-20)\ cm$

$W=m\ cm$

substitute in the formula the given values and solve for m

$4,400=(2m-20)m$

Distribute in the right side

$4,400=2m^2-20m$

$2m^2-20m-4,400=0$

Solve the quadratic equation by graphing

Using a graphing tool

The solution is m=52.17 (the positive value is the solution)

What is the midpoint of the line segment with endpoints (3.2,2.5) and (1.6-4.5)?

NikAS [45]

Answer:

(2.4, -1)

Step-by-step explanation:

To find the midpoints of two points in the format (x,y), we find the mean for the values of x and y.

In this question:

(3.2, 2.5) and (1.6, -4.5)

Mean for the values of x:

(3.2 + 1.6)/2 = 2.4

Mean for the values of y:

(2.5 - 4.5)/2 = -1

Midpoint:

(2.4, -1)
