Answer:
x = 2, x = - 2
Step-by-step explanation:
Step 1:
x² - 4 = 0 Equation
Step 2:
x² = 4 Add 4 on both sides
Step 3:
x = 
Square 4
Answer:
x = 2, x = - 2

Answer:
10, 20, 30, 40, 50, 60
Step-by-step explanation:
you just have to list the multiples

The answer is
B) 2n - 5
because it's -5 than twice the width (2n)
Answer:
The third X is 6. The fourth Y is 4.5
Step-by-step explanation:
The Rule : X is twice as large as Y. Y is half the size of X.
You can get this piece of information by looking at the different values.
For example, y=1 is x=2. This follows the rule. x=4 is y=2.
We have confirmed the rule is true, now we just need to carry the information into the other blocks!
Best of luck on the quiz! Please give brainliest if I helped you out!
KE = 0 (because velocity is 0)
PE = mgh = 2kg*9.8m/s^2*40m= 784 joule
<u>Explanation:</u>
KE stands for kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Since in this case, the building is still and therefore it does not have any kind of kinetic energy because there is not acceleration.
