If the area of one is 20, that the area of 30 is 20*30=600 square inches.
X - y = 8
x + 2 = 3y.....x = 3y - 2
3y - 2 - y = 8
2y = 10
y = 5
x - y = 8
x - 5 = 8
x = 8 + 5
x = 13
so x = 13 and y = 5
I think that the answer is A
Answer:
10485760
Step-by-step explanation:
The explicit formula will be an = 10(4)^n-1
So the 11th term will be a(11) = 10(4)^10 = > 10485760
