Answer:
L = 11 m
Step-by-step explanation:
The perimeter is 40 m, which in turn equals 2L + 2W. With W = 9 m, we have:
40m = 2L + 2(9 m), or 40 m = 2L + 18 m, or 22 m = 2L. Then L = 11 m.

Answer: 3 + 11x
Step-by-step explanation: combine like terms 5 -2 is 3 and 8x + 3x is 11x and they're both positive so it is 3 + 11x
Answer:
45
Step-by-step explanation:
If a(1) = 5, then a(2) = a(1)*3, or 5*3, or 15.
If a(2) = 15, then a(3) = a(2)*3, or a(3) = 15*3 = 45
This is a geometric sequence with first term a(1) = 5 and common ratio 3. We can immediately write the explicit formula
a(n) = 5*3^(n - 1), which correctly predicts that a(3) = 5*3^(3 - 1) = 5*9 = 45
