Answer:
y = 3^(1 + x)
Step-by-step explanation:
Notice that each time x increases by 1, y increases by a factor of 3.
Thus, the required equation has the form y = 3^x.
Check: If x = 0, do we get 3? No. Therefore we must modify the exponent:
y = 3^(1 + x)
Check: If x = 0, do we get 3? 3^(1 + 0) = 3 (correct)
If x = 2, do we get 27? 3(1 + 2) = 3^3 + 27 (correct)
Letter B would be the answer.
2L + 2(1/2L) = 90
2L + L = 90
3L = 90
L = 30
(1/2)(30) = 15
W = 15
CHECK:
30 + 30 + 15 + 15 = 90
