Answer:
<em>A. 21°, 69°</em>
Step-by-step explanation:
If you work by process of elimination all you have to do is take 27 away from the bigger degree of the two and see if it is 2x as much as the smaller degree.
Ex.
1. 69°-27°= 42°, which is 2x as many as 21°.
Answer:
exact area = 25(pi) m^2
approximate area = 78.54 m^2
Step-by-step explanation:
diameter = 10 m
radius = diameter/2 = 10 m / 2 = 5 m
area = (pi)r^2
area = (pi)(5 m)^2
area = 25(pi) m^2
area = 78.54 m^2
Answer:
Cuadrilátero A: 
Cuadrilátero B: 
Step-by-step explanation:
Existen dos formas distintas de determinar las áreas de cada cuadrilátero:
(i) <em>Obtener el área de cada cuadrado y sumar los resultados.</em>
(ii) <em>Calcular los lados del cuadrilátero grande y determinar el área. </em>
Cuadrilátero A
Método (i)


Método (ii)


Cuadrilátero B
Método (i)


Método (ii)


Answer:
3x^2−4x−4
Step-by-step explanation:
3x^2−8x−2+4x−2
=3x^2+−8x+−2+4x+−2
3x^2+−8x+−2+4x+−2
=(3x^2)+(−8x+4x)+(−2+−2)
=3x^2+−4x+−4
Answer:
999.60
Step-by-step explanation:
$3.51 times 42 is 147.42 and 1147.02 minus 147.42 is $999.60
TBH this might not be right I'm not great at math buuut- heeeyy
