Answer:

4,-4

Step-by-step explanation:

4x2-8=56 is our equation.

  1. First we add 8 on both sides to get rid of the "-8" on our equation,we do it on both sides because when you do something on one side of an equation you have to do it on the other.
  2. That will leave us with: 4x2=64
  3. So we will solve our exponent: 4x2
  4. Then we will have: 16x=64 because 4 times 4 is 16
  5. Then we will divide by 16 on both sides to get rid of "16" in "16x"
  6. That will leave us with: x=4 for our answer! :>
  7. I hope this helped.

Deon is going to watch a movie in his collection. He has 10 action movies, 5 comedies, and 8 dramas. He will randomly select one
nadezda [96]

Answer:

the probability that it is not a drama movie is 15/23

Step-by-step explanation:

To calculate the probability we have to make the number of favorable events divided the number of possible events

number of possible events = x

to calculate it we add all the movies

x = 10 + 5 + 8

x = 23

number of favorable events = y

to calculate it we subtract the drama movies from the total of movies

y = x - 8

y = 23 - 8

y = 15

now we divide 15 by 23 and we get the probability

15/23

How do I find the missing sides in this triangle?
stiv31 [10]

Answer:

This is a 30-60-90 triangle so you would do this formula:

Short side (opposite the 30 degree angle) = x.

Hypotenuse (opposite the 90 degree angle) = 2x.

Long side (opposite the 60 degree angle) = x√3.
