30×12×2+6×12×2+30×6×2
=720+144+360
=1224m^2
7+7 = 14 So knowing that 8 is only one more than 7+7 you can do 14 + 1 = 15 ..
Answer: x = 3
Step-by-step explanation:
When the base is the same, the exponents are the same:
3-2x = -x
solve fore x
add 2x to both sides
3-2x = -x
+2x +2x
x = 3
There are 8 students in a art club. There are 3 times as many students in chorus. How many students are in chorus?
We don't know how many students are in chorus. Use n as the students.
n = 8×3
n = 24
The value of n is 24.
So, there are 24 students in chorus.
Answer:
I am not sure what you mean by simplifying to a single power of 3 but 3^6 x 3 would be the power 3 over 7 = 3^7
