The top answer. You can spin the top and get an A and spin the bottom and get 1,2 or 3. Same applies to B
Step-by-step explanation:
The factorisation of 49b^2 - 81 is (7b - 9)(7b + 9). This is because 49 and 81 are the squares of 7 and 9 respectively, so these must be multiplied together. b^2 is b x b. Finally, it must be -9 and +9 to make -81, because when the signs are the same the result is a positive number
H(0)=8. You plug in zero for x you get y=8. So h(0)=8
