2b^2+9
when b=3
First we have to replace b by the number giving
2(3^2)+9
(2)(9)+9
18+9
= 27
I hope that's help !

Original Price: $45
Current price: 45 x 20% - 45
45 x 20% = 9
Always add/subtract by the original number, but since we're finding the price 'decrease', you subtract by the original number.
45 - 9 = 36
Answer: $36
answer:
640,000
step-by-step explanation:
to find the answer, we need to determine whether 41,267 is closer to 40,000 or 50,000.
looking at the numberline, we can conclude that the placement of 641,267 is closer to 640,000, not 650,000.
therefore, the answer is 640,000. (see image attached)
hope this helps :)
