Answer:
The answer would be six.
Step-by-step explanation:
The formula for an arithmetic sequence is An=A1+(n-1)d.
Using this knowledge, you can set up the equation easily to be An=1+(12-1)-5
You then simplify this to 1-55 using PEMDAS, giving you the answer for the twelfth term being -54, you then do this for every term if you want (or you could just subtract 5 by the terms after 14 till you get to -54. After all that, you add the twelve terms up to get -319 as your final answer
Answer:
84
Step-by-step explanation:
3 times 4= 12
12 times 7= 84
Since you don't have the picture, I can explain how to do the problem. Then, you can select the correct answer.
To find the area of a parallelogram, you must multiply the base times the height. If you have those 2 values, just multiply them and you will be done.
6 1/2 ÷ 2 3/4
6 1/2 × 2 4/3
6×2 = 12 , 1/2 × 4/3 = 4/6 = 2/3
Answer = 12 2/3
