X = 180° - (73° + 42°)

= 180° - 115°

X = 65°

Y = 180° - 131°

Y = 49°

→ 180° - (X + Y) =

→ 180° - (65° + 49°) =

→ 180° - 114° = 66°

Z = 180° - 66°

Z = 114°

Clea attends music lessons every 2 weeks, dance class every 3 weeks, and has a dental appointment every 6 weeks. If she attends
Basile [38]
In 6 weeks.



For this problem, you need to determine the least common multiple of the numbers given which is 2, 3, and 6. You can calculate the LCM of multiple numbers by pairs.



The LCM of 2 and 3 is 6 because 6 is the smallest possible number that can be evenly divided by both 2 and 3.



Now you need the LCM of 6 and 6. Which is also 6, because 6 is the smallest number that can be evenly divided by 6.



So the LCM of 2, 3, and 6 is 6. So in 6 weeks, Clea will once again have a music less, attend dance class, and have a dental appointment, all during the same week.

What are the solutions to the equation? x^2+6x = 40.
GaryK [48]

Answer:

x = 4, -10

Step-by-step explanation:

Find the zeros of the equations.

Solve the equation:

x^2 + 6x = 40

Subtract -40 from both sides.

x^2 + 6x - 40 = 0

Factor the equation.

(x - 4)(x + 10)

Solve for x with the given information by equaling it to 0.

x - 4 = 0

Add 4 to both sides

x = 4

x + 10 = 0

Subtract 10 from both sides

x = -10

This means that our x values are:

x = 4, -10
