First, you are going to distribute the 3 into the (6x+2x) and the 8 into the (5x+6). After that, the parenthesis should be gone. Then, move all the x values to one side, and the constants to the other. Then, solve as you normally would.
Answer:
r = radius of circle
Step-by-step explanation:
The circumference of a circle is given by :
C = 2πr
Where
r is the radius of the circle
In this problem, we need to say that what does r represents in the given formula. It means we can say that r stands for the radius of the circle.
To make it easier, aprox pi=3.14
area=pir^2
36=area
36=pir^2
divide both sides by pi
36/pi=r^2
36/3.14=r^2
11.464=r^2
square root both sides
3.39=r
circumfernce=2pir
r=3.39
circumfrence=2pi times 3.39
circumference=pi times 6.78
circumference=3.14 times 6.78
circumfernce=21.29
answer is
circumference=21.29 in
2) 100
3) 49
4) 19
5) idk
6) idk
7) 7
60 divided by 4.
EXPLANATION:
If his grandfathers age is 3 more than whatever 4 times seans age is. we can do 63 - 3. which is 60.
Then you fond seans age. 60 divided by 4 is the equation to find seans age.
sry its a bad explanation but I hope the answer helps!
