What is the expression obtained when the sum of 2a−16abc−45 and 2a+7abc+11 is subtracted from 6a+6abc−30?

see explain

Step-by-step explanation:6a + 6abc -30 4a - 9abc -34 is the sumsubtract to get 2a+15abc +4

Step-by-step explanation:

Add the first 2 trinomials

2a - 16abc - 45 + 2a + 7abc + 11

2a + 2a - 16abc + 7abc - 45 + 11          Combine like terms

4a - 9abc + 56

Now you want to subtract this answer from the third trinomial.

6a + 6abc - 30 - (4a - 9abc +56)           Remove the brackets.

6a + 6abc - 30 - 4a + 9abc - 56            Rearrange so  like terms are together

6a - 4a + 6abc + 9abc - 40 - 56            Combine

2a + 15abc - 106

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
