Which of the following equations is equivalent to 3(a + 4) – 5(a – 2) = 22?
Group of answer choices

-2a + 2 = 22

8a + 2 = 22

8a + 22 = 22

-2a + 22 = 22

Answers

-2a+2=22 is the correct answer
The answer is -2a+22=22 because 3 times a is 3a. -5 times a is -5a is you get -2a. 3 times 4 is 12 and -5 times -2 is 10 so you get 22. That adds up to -2a+22=22 with also makes a equal to 0.

Moving an object at a faster speed is doing more work than moving an object at a slower speed (same distance for both). True or false?

Answers

Answer:

false

Step-by-step explanation:

explanation:

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
