Answer:
Step-by-step explanation:
x / 2.25 seconds = 28 times / 12 seconds
multiply by sides by 2.25 seconds
x / 2.25 seconds * 2.25 seconds = 28 times / 12 seconds * 2.25 second
x = 2.3333333 times/ second * 2.25 seconds
x = 5.8333
Answer:
The perimeter of this rectangle is 14x + 10
Step-by-step explanation:
You want to add all of the sides together.
First, you add 4x-2 and 3x+7
4x-2 + 3x+7 = 7x+5
Then, you multiply this answer by two, since there are two of each side with each value.
(7x+5) * 2
7x * 2 = 14x
5*2 = 10
So, (7x+5) * 2 = 14x + 10
14x + 10 is your final answer
