Answer:
So in order to find the missing number, we must find the difference with the numbers that we were given.
Problem #1
42-30= 12 and 84-69= 15. It's possible that each difference increases by one Let's see...
30+12= 42
42+13= 55
55+14 = 69
69+15 = 84
So for 1., all you have to do is keep adding the difference and increase it by 1 each time. If you wanted to keep increasing, you would add 84+16, then 100+17, etc.
Problem #2: As for the second one, I had trouble solving it, sorry :(.
Problem #3
3. For the third problem, 27-22= 5 and 9-1=8. It looks like each difference increased by 1.
27-22 = 5
22-6 = 16
16-7 = 9
9-8= 1
Here ya go.
-n - 6n + 4 = 53
(Combine like terms)
-7n + 4 = 53
-7n = 53 - 4
-7n = 49
n = -7
14 = 6n + 6 - 2n
(Combine like terms)
14 = 14n + 6
-4n = 6 - 14
-4n = -8
n = 2

d=sqrt(36+25)
d=sqrt(61)
d= around 7.8
Find length of BC
d=sqrt((4-(-4))^2+(10-5)^2)
d=sqrt(8^2+5^2)
d=sqrt(64+25)
d=sqrt(89)
d= around 9.4
Find length CD
d=sqrt((8-4)^2+(7-10)^2)
d=sqrt(4^2+(-3)^2)
d=sqrt(16+9)
d=sqrt(25)
d=5
Find length DE
d=sqrt((4-8)^2+(5-7)^2)
d=sqrt((-4)^2+(-2)^2)
d=sqrt(16+4)
d=sqrt(20)
d= around 4.5
Find length EA
d=sqrt ((4-2)^2+(5-0)^2 )
d=sqrt(2^2+5^2)
d=sqrt(4+25)
