Answer:
12, 17, 24
Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the rule, that is
T₁ = 1² + 2(1) + 9 = 1 + 2 + 9 = 12
T₂ = 2² + 2(2) + 9 = 4 + 4 + 9 = 17
T₃ = 3² + 2(3) + 9 = 9 + 6 + 9 = 24
The difference between the two cities are that each temp is different their 14c away because their is a minus on the eight
-2x-4
slope always goes first and behind that goes x...
the ratio is 6 to 9, 9 out of (6+9) 15 bicycles will be black.
25 * 9/15 = 15
there will be 15 black bicycles
