Which function describes the sequence 3, 6, 12, 24, ... for n = 1, 2, 3, ...?
• A f(n) = 3n
© B. f(n) = 2" +1
O
C. f(n) = 3 - 2n-1
• D. f(n) = (n − 1)² +3

a) 32pie square meters

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
