Division by zero is undefined. That is a impossible question
Let w = cos(x)
The given equation turns into -5w^2 + 4w + 1 = 0. Use the quadratic formula to find that the two solutions, in terms of w, are:
The solution w = 1 leads to cos(x) = 1 which then becomes x = 0, x = 2pi, x = 4pi, etc. The general way to write this is x = 2pi*n where n is any integer. These angles are in radian mode.
The solution w = -0.2 leads to cos(x) = -0.2 which becomes x = arccos(-0.2) = 1.77215 approximately assuming your teacher wants the angle in radian mode. Unfortunately, I don't know the exact value of x here. There may not be an exact value, or finding this exact value may be well beyond the scope of this course.
Answer:
Equilátero si todos sus lados son iguales o isósceles si la base es menor que sus otros dos lados.
Step-by-step explanation:

Comienzas dibujando la línea de 6 cm. Luego encuentras su mediatríz, la cual está a 3 centímetros de cualquier extremo de la línea.
Luego dibujas el triángulo como se muestra en el dibujo. Dependiendo de la longitud de los lados, el triángulo podría ser equilátero si todos sus lados son iguales o isósceles si solo los dos lados inclinados son iguales y la base es diferente.
Answer:
You add the parts then subtract them with the old part
Step-by-step explanation:
If you were to grill two hamburgers at the same it would take 5 minutes to grill one side of 2 hamburgers and ten minutes to grill 2 ham burgers on both sides. So 10 minutes would make two hamburgers while 20 minutes will cook 4 hamburgers than add and extra 10 minutes to cook the last hamburger on both sides.
10 minutes = 2 both side cooked hamburgers
+
10 minutes = 2 both side cooked hamburgers
+
an extra 10 minutes = another both side cooked hamburgers since we only need five
=
30 minutes in minimal time to cook five hamburgers
