Step-by-step explanation:
3a-3(a+2)=10
3a-3a-6=10
+3 +3
6a-6=10
+6 +6
6a=16
277 squared above the perimeter of the circular building find the markings of both sides
Answer:
16
since it's the least that can be divided by both
Answer: 
Step-by-step explanation:
The average speed of the car is 40 miles per hour:

The car drives for 45 minutes:

Since 1 hours has 60 minutes, we can convert the time from minutes to hours:

Knowing these values, we can use the following formula for calculate the distace "d":

Therefore, substituting values into the formula, we get:

Answer:
The first option is the answer (k = +/- 2 square root of J)
Step-by-step explanation:
Since you need to leave k by itself, You multiply both sides by 4 which will leave you with 4J=k^2. To get rid of the square(^2), you need to square root both sides which will leave k by it self. So now you have 4J inside the square root = k. The last step is to take the square root of 4 (which is + or -2) and put it outside the square root sign, leaving J inside the square root.
