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

where
L is the length
W is the width
we have



substitute in the formula the given values and solve for m

Distribute in the right side


Solve the quadratic equation by graphing
Using a graphing tool
The solution is m=52.17 (the positive value is the solution)
see the attached figure
Answer: Basic Function
Step-by-step explanation: Why Basic Function is the simplest function type because then you can do functional things more similar and easier
Answer:
1/3 + 3/4 + 4/6 +1/2 =
Step-by-step explanation:
1/6 + 4/6 = 5/6
3/4 + 1/4 = 4/4
5/6 + 4/4 = 9/12
C! x = 28. If you use simplification, and then you find the answer and use it in the equation, it would be correct.
Answer
Find out the value of x .
To proof
SAS congurence property
In this property two sides and one angle of the two triangles are equal.
in the Δ ADC and ΔBDC
(1) CD = CD (common side of both the triangle)
(2) ∠CDA = ∠ CDB = 90 °
( ∠CDA +∠ CDB = 180 ° (Linear pair)
as given in the diagram
∠CDA = 90°
∠ CDB = 180 ° - 90°
∠ CDB = 90°)
(3) AD = DB (as shown in the diagram)
Δ ADC ≅ ΔBDC
by using the SAS congurence property .
AC = BC
(Corresponding sides of the congurent triangle)
As given
the length of AC is 2x and the length of BC is 3x - 5 .
2x = 3x - 5
3x -2x =5
x = 5
The value of x is 5 .
Hence proved
