Answer:

a = -4

b = 3

c = 6

Step-by-step explanation:

x^2 + 8x = 38

We take the coefficient of the x term

Divide by 2 and then square it

8/2 =4

4^2 = 16

Add 16 to both sides

x^2 +8x + 16 = 38 + 16

x^2 +8x +16 = 54

Take b/2 and use it in the the (x+b/2)^2

(x+4)^2 = 54

Take the square root of each side

sqrt((x+4)^2) = ± sqrt(54)

x+4 =  ± sqrt(54)

Subtract 4 from each side

x+4-4 = -4  ± sqrt(54)

x = -4  ± sqrt(54)

Simplify the square root

x = -4  ± sqrt(9*6)

x = -4 ± sqrt(9) sqrt(6)

x = -4 ± 3 sqrt(6)

Delicious77 [7]

The right answer is Option B.

Step-by-step explanation:

Given,

Length of movie = 106 minutes

Time taken to get to theater = x minutes

Time taken to get back = x minutes

Total time = x+x = 2x minutes

Total time = 154 minutes

According to given statement;

Time taken to get to and get back + Length of movie = Total time

2x+106=154

154=2x+106

The equation 154=2x+106 describes the time it takes Ingrid to get to the movie theater.

The right answer is Option B.

Give three pros and cons of getting a pug, and the same for a poodle.
balu736 [363]

Answer:

Step-by-step explanation:

pugs;

pros= Pugs are small in size and thus, making them suitable for small-sized rooms or apartments. Pugs have a friendly and lapdog temperament, get along well with most people and pets. Pugs are low to medium-shed breeds, which implies you are less likely going to be troubled with shedding.

cons= Pugs are prone to various throats, ears, eyes, folds, facial infections, and breathing troubles; hence they will require regular health check-ups. Pug dogs are not highly trainable – it will be difficult to train a pug to do not-so-easy activities even if you hire a professional.

poodle;

pros=They don't shed. Poodles have long hair, instead of fur so they do not shed. ...

They're easy to train. The poodle's intelligence and eagerness to please make them easy to train. ...

They're good with children or other dogs. ...

They make great service dogs or therapy dogs.

cons= Their hair requires some serious maintenance. Because poodles can grow their hair long, they require a lot more maintenance than breeds with short, flat coats. ...

They require a lot of mental stimulation. ...

They can be emotionally sensitive.
