Answer:
3/40
Step-by-step explanation:
Therefore, the answer is 3/40!
Surface area = 2(12*12+15*12+15*12) = 1008
1008 * 4 = 4032
You first find the average of the first two test scores. When you find the average, you add the two numbers together and then divide by two which gives you 89. You then plug in different scores above the number 89 and find the average of those (89 and x) to see which gives you an average of 92. It’s mostly a guess and check type of problem.
First you need to pick a number for y. Lets say you pick 0
Then you need to +3 to each side
Then you can say 3=x+2 or -3=x+2.
To find x you need to subtract 2.
You answer would be (1,3) and (-5.-3)
(LCM is 40)
