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

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
Given:
hexagon
apothem of the hexagon: 14 cm
perimeter of the hexagon: 96 cm
Area of the hexagon = [(3√3) / 2] a² ; where a is the measure of the side
hexagon has 6 sides.
Perimeter = 6a
96 cm = 6a
96 cm / 6 = a
16 = a
We can also use the area of a triangle to approximate the area of the hexagon. There are 6 triangles in the hexagon .
Area of a triangle = (height * base) / 2
A = (14 cm * 16 cm) / 2
A = 224 / 2
A = 112 cm²
112 cm² * 6 triangles = 672 cm²
Answer:
x = 26°
Step-by-step explanation:
The measure of the secant- secant angle x is one- half the difference of the measures of the intercepted arcs , larger subtract smaller
x =
(66° - 14°) = 0.5 × 52° = 26°
Because there are only two things you can do with these two " family" members. 81 divided by 9 is 9. 9 times 9 is 81. Strictly speaking, there should be three in the family: 9,9 and 81 9 is the square root of 81. 81 is the 9 squared.
